1. Java, World Wide Web, and Beyond (P. 13)

Today Java is used for:
Web Programming
Developing standalone applications across platforms on
and mobile devices
Developing the code to communicate with and control the robotic rover that rolled on Mars.

2. Characteristics of Java (P. 16)

Java particular feature is to write a program once and run it everywhere.
Object-oriented

Distributed

Interpreted

Architecture-neutral
High-performance

Multithreaded

Easier than C++
Replace multiple inheritance in C++ with a simple language construct called an interface
Eliminate pointers
Use automatic memory allocation and garbage collection
Easy to write and read

Object-Oriented

Replace traditional procedure programming techniques.
OOP models the real world in terms of objects.
Central issue in software development is how to reuse code.
OOP provides great flexibility, modularity, clarity and reusability through encapsulation, inheritance, and polymorphism.
Several computers working together on a network.
Java is designed to make distributed computing easy.
Writing network programs in Java is like sending and receiving data to and from a file.
Unlike conventional language translators
Compiler converts source code into a machine-independent format (Byte code)
allow it to run on any computer H/W that has the Java runtime system (Java Virtual Machine)
Means reliable.
Java has a runtime exception-handling feature.
Java forces the programmer to write the code to deal with exceptions.
Java can catch and respond to an exceptional situation
so the program can continue its normal execution
and terminate gracefully when a runtime error occurs.
As an Internet programming language, Java is used in a networked and distributed environment.
If you download a Java applet and run it on your computer, it will not damage your system.

Architecture-Neutral

As Java is interpreted, this feature enables Java to be architecture-neutral or platform-independent.
Using Java, developers need to write only one version of software so it can run on every platform (Windows, OS/2, Macintosh, and various UNIX, IBM AS/400, and IBM mainframes).
Because Java is architecture-neutral, Java programs are portable.
They can be run on any platform without being recompiled.

Performance

Design well to perform on very low-power CPUs
Easy to translate directly to native machine code
Multithreading is a program’s capability to perform several tasks simultaneously (e.g: Downloading a video file while playing the video).
Multithreading is particularly useful in GUI programming (e.g: a user can listen to an audio recording while surfing the Web page) and network programming (e.g: A server can serve multiple clients at the same time).
Libraries can freely add new methods and instance variables.
New class can be loaded on the fly without recompilation.

3. The Java Language Specification, API, JDK, and IDE (P. 19)

Computer languages have strict rules of usages.
If you do not follow the rules when writing a program, the computer will be unable to understand it.
Java language specification and Java API define the Java standard.

Java Language specification & API

Java Language specification is a technical definition of the language that includes the syntax and semantics of the Java programming language.
The application programming interface (API) contains predefined classes and interfaces for developing Java programs.
The Java language specification is stable, but the API is still expanding.

Java API Editions

There are 3 editions of Java API: Java 2 Standard Edition (J2SE), Java 2 Enterprise Edition (J2EE) and Java 2 Micro Edition (J2ME).
J2SE: used to develop client-side standalone applications or applets.
J2EE: used to develop server-side applications, such as Java servlets and JavaServer Pages.
J2ME: used to develop applications for mobile devices, such as cell phones.

Java Development Toolkit (JDK)

For J2SE 5.0, the Java Development Toolkit is called JDK5.0, formerly known as JDK1.5.
JDK consists of a set of separate programs for developing and testing Java programs, each of which is invoked from a command line.
Besides JDK, there are more than a dozen Java development tools such as JBuilder, NetBeans, Sun ONE, Eclipse, JCreator, … These tools provide an integrated development environment (IDE) for rapidly developing Java programs (Editing, compiling, building, debugging and online help).

4. A Simple Java Program (P. 20)

There are 2 Java Programs: Java Applications and applets.
Java Applications can be executed from any computer with a Java interpreter.
Java applets can be run directly from a Java-compatible Web browser. Applets are suitable for deploying Web projects.

A simple java applicationcode

// This application program prints Welcome to Java!

public class Welcome {

public static void main(String[] args){

System.out.println( "Welcome to Java!" );

Class heading

Main method signature

5. Creating, Compiling, and Executing a Java Program (P. 21)

You have to create your program and compile it before it can be executed.
If your program has compilation errors, you have to fix them by modifying the program then recompile it.
If your program has runtime errors or does not produce the correct result, you have to modify the program, recompile it and execute it again.

6. Anatomy of the Java Program (P. 23)

The previous sample code has the following components:
Reserved words
The main method
Comments help programmers and users to communicate and understand the program.
Comments are ignored by the compiler.
A line comment: //
A paragraph comment: /*…*/

// This application prints Welcome!

/* This application prints Welcome!*/

/* This application prints

Reserved Words

Reserved Words or Keywords are words that have a specific meaning to the compiler and cannot be used for other purpose in the program.
E.g: class, public, static, void are keywords
Java uses certain reserved words called modifiers that specify the properties of the data, methods and classes and how they can be used.
E.g: public, static, private, final, abstract and protected
A statement represents an action or a sequence of actions.
The statement Systemout.println(“Welcome to Java!”) in previous code is a statement to display the greeting “Welcome to Java!”.
Every statement in Java ends with a semicolon (;).
The braces in the program form a block that groups the components of the program.
A block begins with ({) and ends with (}).
Every method has a method block that groups the statements in the method.
Blocks can be nested.

public class Test{

System.out.println(“Welcome to java!”);

Class block

Method block

The class is the essential Java construct.
To program in Java, you must understand classes and be able to write and use them.
A program is defined by using one or more classes.
Method consists of a collection of statements that perform a sequence of operations.
E.g: System.out.println?
System.out: the standard output object
println: the method in the object which to displays a message to the standard output device.

The main Method

Every Java application must have a user-declared main method that defines where the program begins.
The Java interpreter executes the application by invoking the main method.
The main method looks like this:
//Statemtns;

How to write Java applications

Two types of Java Program

Applet Program
Program which is running on Web Browser
Use Appletviewer or internet explorer
Application program
Typical application program
Execute using interpreter named “java”

Checkpoints for the Beginner

Java differentiates the upper- and lower- cases.
File differentiates the upper- and lower- cases.
Should set the environment variables correctly.
Run the program including main()
The format of main is always� public static void main (String args[])
Or public static void main (String[] args)
Applet class is always public.

Checkpoints for the Beginner (Cont.)

One file can have only one “public” class.�– compile error.
If there is a class declared “public”, then the file name should be same as that public class name.
Constructor doesn’t have a return type and has the same name as the class name.
There is no comma between width and height in the HTML file.��<applet code=class-file-name width=300 height=200>�</applet>

Rules of naming the class and method

English Noun type
Starts with upper-case letter
Coming multiple nouns : not with “_” , combine with another Uppercase.
Ex. Car, ChattingServer
Method Name
English Verb type
Starts with lower-case letter
Ex. getName(), setLabel()

Input and Output Statements

Printing a Line of Text Example (Welcome1.java)

// Welcome1.java

// Text-printing program.

public class Welcome1 {

// main method begins execution of Java application

public static void main( String args[] )

System.out.println( “Welcome to Java Programming!” );

} // end method main

} // end class Welcome1

Printing a Line of Text (Cont.)

Compiling a program

Open a command prompt window, go to directory where program is stored
Type javac Welcome1.java
If no errors, Welcome1.class created
Has bytecodes that represent application
Bytecodes passed to Java interpreter
Executing a program
Type java Welcome1
Interpreter loads .class file for class Welcome1
.class extension omitted from command
Interpreter calls method main

Modifying Our First Java Program

Modify example in Welcome1.java to print same contents using different code
Modifying programs
Welcome2.java produces same output as Welcome1.java
Using different code�System.out.print( "Welcome to " ); System.out.println( "Java Programming!" );
System.out.print( "Welcome to " ) displays “Welcome to ” with cursor remaining on printed line
System.out.println( "Java Programming!" ) displays “Java Programming!” on same line with cursor on next line

Example (Welcome2.java)

// Welcome2.java

public class Welcome2 {

System.out.print( “Welcome to ” );

System.out.println( “Java Programming!” );

} // end class Welcome2

Modifying Our First Java Program (Cont.)

Newline characters (\n)

Interpreted as “special characters” by methods System.out.print and System.out.println
Indicates cursor should be on next line
Welcome3.java�System.out.println( "Welcome\nto\nJava\nProgramming!" );
Line breaks at \n
Can use in System.out.println or System.out.print to create new lines

System.out.println( "Welcome\nto\nJava\nProgramming!" );

Example (Welcome3.java)

// Welcome3.java

public class Welcome3 {

} // end class Welcome3

Escape characters
Backslash ( \ ) indicates special characters to be output






	For example System.out.println( "\"in quotes\"" ); Displays "in quotes"

Displaying Text in a Dialog Box

Most Java applications use windows or a dialog box
We have used command window
Class JOptionPane allows us to use dialog boxes
Set of predefined classes for us to use
Groups of related classes called packages
Group of all packages known as Java class library or Java applications programming interface (Java API)
JOptionPane is in the javax.swing package
Package has classes for using Graphical User Interfaces (GUIs)

Displaying Text in a Dialog Box (Cont.)

Upcoming program
Application that uses dialog boxes
Explanation will come afterwards
Demonstrate another way to display output
Packages, methods and GUI

Example (Welcome4.java)

// Welcome4.java

// Printing multiple lines in a dialog box.

// Java packages

import javax.swing.JOptionPane; // program uses JOptionPane

public class Welcome4 {

JOptionPane.showMessageDialog(

null , "Welcome\nto\nJava\nProgramming!" );

System.exit( 0 );

// terminate application with window

} // end class Welcome4

Another Java Application : Adding Integers

Use input dialogs to input two values from user
Use message dialog to display sum of the two values

Example (Addition.java)

// Addition.java

// Addition program that displays the sum of two numbers.

public class Addition {

String firstNumber; // first string entered by user

String secondNumber; // second string entered by user

int number1; // first number to add

int number2; // second number to add

int sum; // sum of number1 and number2

// read in first number from user as a String

firstNumber = JOptionPane.showInputDialog( "Enter first integer" );

// read in second number from user as a String

secondNumber =

JOptionPane.showInputDialog( "Enter second integer" );

Example (Addition.java) (Cont.)

// convert numbers from type String to type int

number1 = Integer.parseInt( firstNumber );

number2 = Integer.parseInt( secondNumber );

// add numbers

sum = number1 + number2;

// display result

JOptionPane.showMessageDialog( null , "The sum is " + sum, "Results" ,� JOptionPane.PLAIN_MESSAGE );

System.exit( 0 ); // terminate application with window

} // end class Addition

Course Syllabus UNIT CONCEPTS to be covered UNIT-I JAVA Basics UNIT-II Inheritance UNIT-III Data structures creation and manipulation in java UNIT-IV Exception Handling UNIT-V GUI Programming With JAVA http://professional-guru.com

JAVA Basics http://professional-guru.com

Why Java is Important • Two reasons : – Trouble with C/C++ language is that they are not portable and are not platform independent languages. – Emergence of World Wide Web, which demanded portable programs • Portability and security necessitated the invention of Java http://professional-guru.com

History • James Gosling - Sun Microsystems • Co founder – Vinod Khosla • Oak - Java, May 20, 1995, Sun World • JDK Evolutions – JDK 1.0 (January 23, 1996) – JDK 1.1 (February 19, 1997) – J2SE 1.2 (December 8, 1998) – J2SE 1.3 (May 8, 2000) – J2SE 1.4 (February 6, 2002) – J2SE 5.0 (September 30, 2004) – Java SE 6 (December 11, 2006) – Java SE 7 (July 28, 2011) http://professional-guru.com

Cont.. • Java Editions. J2SE(Java 2 Standard Edition) - to develop client-side standalone applications or applets. J2ME(Java 2 Micro Edition ) - to develop applications for mobile devices such as cell phones. J2EE(Java 2 Enterprise Edition ) - to develop server-side applications such as Java servlets and Java ServerPages. http://professional-guru.com

What is java? • A general-purpose object-oriented language. • Write Once Run Anywhere (WORA). • Designed for easy Web/Internet applications. • Widespread acceptance. http://professional-guru.com

How is Java different from C… • C Language: – Major difference is that C is a structure oriented language and Java is an object oriented language and has mechanism to define classes and objects. – Java does not support an explicit pointer type – Java does not have preprocessor, so we cant use #define, #include and #ifdef statements. – Java does not include structures, unions and enum data types. – Java does not include keywords like goto, sizeof and typedef. – Java adds labeled break and continue statements. – Java adds many features programming. required for object oriented http://professional-guru.com

How is Java different from C++… • C++ language Features removed in java: Java doesn’t support pointers to avoid unauthorized access of memory locations. Java does not include structures, unions and enum data types. Java does not support operator over loading. Preprocessor plays less important role in C++ and so eliminated entirely in java. Java does not perform automatic type conversions that result in loss of precision. http://professional-guru.com

Cont…  Java does not support global variables. Every method and variable is declared within a class and forms part of that class.  Java does not allow default arguments.  Java does not support inheritance of multiple super classes by a sub class (i.e., multiple inheritance). This is accomplished by using ‘interface’ concept.  It is not possible to declare unsigned integers in java.  In java objects are passed by reference only. In C++ objects may be passed by value or reference. http://professional-guru.com

Cont … New features added in Java:  Multithreading, that allows two or more pieces of the same program to execute concurrently.  C++ has a set of library functions that use a common header file. But java replaces it with its own set of API classes.  It adds packages and interfaces.  Java supports automatic garbage collection.  break and continue statements have been enhanced in java to accept labels as targets.  The use of unicode characters ensures portability. http://professional-guru.com

Cont … Features that differ:  Though C++ and java supports Boolean data type, C++ takes any nonzero value as true and zero as false. True and false in java are predefined literals that are values for a boolean expression.  Java has replaced the destructor function with a finalize() function.  C++ supports exception handling that is similar to java's. However, in C++ there is no requirement that a thrown exception be caught. http://professional-guru.com

Characteristics of Java • Java is simple • Java is architecture-neutral • Java is object-oriented • Java is portable • Java is distributed • Java’s performance • Java is interpreted • Java is multithreaded • Java is robust • Java is dynamic • Java is secure http://professional-guru.com

Java Environment • Java includes many development tools, classes and methods – Development tools are part of Java Development Kit (JDK) and – The classes and methods are part of Java Standard Library (JSL), also known as Application Programming Interface (API). • JDK constitutes of tools like java compiler, java interpreter and many. • API includes hundreds of classes and methods grouped into several packages according to their functionality. http://professional-guru.com

Java is architecture-neutral JAVA Program Execution http://professional-guru.com

WORA(Write Once Run Anywhere) http://professional-guru.com

Editplus for Java Programming • Edit Plus Software: • EditPlus is a 32-bit text editor for the Microsoft Windows operating system. • The editor contains tools for programmers, including syntax highlighting (and support for custom syntax files), file type conversions, line ending conversion (between Linux, Windows and Mac styles), regular expressions for search-and-replace, spell check etc). http://professional-guru.com

It's finally here:

>> The Road to Membership and Baeldung Pro .

Going into ads, no-ads reading , and bit about how Baeldung works if you're curious :)

Azure Container Apps is a fully managed serverless container service that enables you to build and deploy modern, cloud-native Java applications and microservices at scale. It offers a simplified developer experience while providing the flexibility and portability of containers.

Of course, Azure Container Apps has really solid support for our ecosystem, from a number of build options, managed Java components, native metrics, dynamic logger, and quite a bit more.

To learn more about Java features on Azure Container Apps, visit the documentation page .

You can also ask questions and leave feedback on the Azure Container Apps GitHub page .

Java applications have a notoriously slow startup and a long warmup time. The CRaC (Coordinated Restore at Checkpoint) project from OpenJDK can help improve these issues by creating a checkpoint with an application's peak performance and restoring an instance of the JVM to that point.

To take full advantage of this feature, BellSoft provides containers that are highly optimized for Java applications. These package Alpaquita Linux (a full-featured OS optimized for Java and cloud environment) and Liberica JDK (an open-source Java runtime based on OpenJDK).

These ready-to-use images allow us to easily integrate CRaC in a Spring Boot application:

Improve Java application performance with CRaC support

Modern software architecture is often broken. Slow delivery leads to missed opportunities, innovation is stalled due to architectural complexities, and engineering resources are exceedingly expensive.

Orkes is the leading workflow orchestration platform built to enable teams to transform the way they develop, connect, and deploy applications, microservices, AI agents, and more.

With Orkes Conductor managed through Orkes Cloud, developers can focus on building mission critical applications without worrying about infrastructure maintenance to meet goals and, simply put, taking new products live faster and reducing total cost of ownership.

Try a 14-Day Free Trial of Orkes Conductor today.

To learn more about Java features on Azure Container Apps, you can get started over on the documentation page .

And, you can also ask questions and leave feedback on the Azure Container Apps GitHub page .

Whether you're just starting out or have years of experience, Spring Boot is obviously a great choice for building a web application.

Jmix builds on this highly powerful and mature Boot stack, allowing devs to build and deliver full-stack web applications without having to code the frontend. Quite flexibly as well, from simple web GUI CRUD applications to complex enterprise solutions.

Concretely, The Jmix Platform includes a framework built on top of Spring Boot, JPA, and Vaadin , and comes with Jmix Studio, an IntelliJ IDEA plugin equipped with a suite of developer productivity tools.

DbSchema is a super-flexible database designer, which can take you from designing the DB with your team all the way to safely deploying the schema .

The way it does all of that is by using a design model , a database-independent image of the schema, which can be shared in a team using GIT and compared or deployed on to any database.

And, of course, it can be heavily visual, allowing you to interact with the database using diagrams, visually compose queries, explore the data, generate random data, import data or build HTML5 database reports.

Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.

But these can also be overused and fall into some common pitfalls.

1. Introduction

In this article, we’ll see how we can create a presentation using Apache POI .

This library gives us a possibility to create PowerPoint presentations, read existing ones, and to alter their content.

2. Maven Dependencies

To begin, we’ll need to add the following dependencies into our pom.xml :

The latest version of both libraries can be downloaded from Maven Central.

3. Apache POI

The Apache POI library supports both .ppt and .pptx files , and it provides the HSLF implementation for the Powerpoint ’97(-2007) file format and the XSLF for the PowerPoint 2007 OOXML file format.

Since a common interface doesn’t exist for both implementations, we have to remember to use the XMLSlideShow , XSLFSlide and XSLFTextShape classes when working with the newer .pptx file format .

And, when it’s required to work with the older .ppt format, use the HSLFSlideShow , HSLFSlide and HSLFTextParagraph classes.

We’ll use the new .pptx file format in our examples, and the first thing we have to do is create a new presentation, add a slide to it (maybe using a predefined layout) and save it.

Once these operations are clear, we can then start working with images, text, and tables.

3.1. Create a New Presentation

Let’s first create the new presentation:

3.2. Add a New Slide

When adding a new slide to a presentation, we can also choose to create it from a predefined layout. To achieve this, we first have to retrieve the XSLFSlideMaster that holds layouts (the first one is the default master):

Now, we can retrieve the XSLFSlideLayout and use it when creating the new slide:

Let’s see how to fill placeholders inside a template:

Remember that each template has its placeholders, instances of the XSLFAutoShape subclass, which could differ in number from one template to another.

Let’s see how we can quickly retrieve all placeholders from a slide:

3.3. Saving a Presentation

Once we’ve created the slideshow, the next step is to save it:

4. Working With Objects

Now that we saw how to create a new presentation, add a slide to it (using or not a predefined template) and save it, we can start adding text, images, links, and tables.

Let’s start with the text.

When working with text inside a presentation, as in MS PowerPoint, we have to create the text box inside a slide, add a paragraph and then add the text to the paragraph:

When configuring the XSLFTextRun , it’s possible to customize its style by picking the font family and if the text should be in bold, italic or underlined.

4.2. Hyperlinks

When adding text to a presentation, sometimes it can be useful to add hyperlinks.

Once we have created the XSLFTextRun object, we can now add a link:

4.3. Images

We can add images, as well:

However, without a proper configuration, the image will be placed in the top left corner of the slide . To place it properly, we have to configure its anchor point:

The XSLFPictureShape accepts a Rectangle as an anchor point, which allows us to configure the x/y coordinates with the first two parameters, and the width/height of the image with the last two.

Text, inside of a presentation, is often represented in the form of a list, numbered or not.

Let’s now define a list of bullet points:

Similarly, we can define a numbered list:

In case we’re working with multiple lists, it’s always important to define the indentLevel to achieve a proper indentation of items.

4.5. Tables

Tables are another key object in a presentation and are helpful when we want to display data.

Let’s start by creating a table:

Now, we can add a header:

Once the header is completed, we can add rows and cells to our table to display data:

When working with tables, it’s important to remind that it’s possible to customize the border and the background of every single cell.

5. Altering a Presentation

Not always when working on a slideshow, we have to create a new one, but we have to alter an already existing one.

Let’s give a look to the one that we created in the previous section and then we can start altering it:

5.1. Reading a Presentation

Reading a presentation is pretty simple and can be done using the XMLSlideShow overloaded constructor that accepts a FileInputStream :

5.2. Changing Slide Order

When adding slides to our presentation, it’s a good idea to put them in the correct order to have a proper flow of slides.

When this doesn’t happen, it’s possible to re-arrange the order of the slides. Let’s see how we can move the fourth slide to be the second one:

5.3. Deleting a Slide

It’s also possible to delete a slide from a presentation.

Let’s see how we can delete the 4th slide:

6. Conclusion

This quick tutorial has illustrated how to use the Apache POI API to read and write PowerPoint file from a Java perspective.

The complete source code for this article can be found, as always, over on GitHub .

How to Create a MS PowerPoint Presentation in Java with a Maven Project?

In the software industry, presentations play a major role as information can be conveyed easily in a presentable way via presentations. Using Java, with the help of Apache POI, we can create elegant presentations. Let us see in this article how to do that.

Necessary dependencies for using Apache POI:

It has support for both .ppt and .pptx files. i.e. via

HSLF implementation is used for the Powerpoint 97(-2007) file format
XSLF implementation for the PowerPoint 2007 OOXML file format.

There is no common interface available for both implementations. Hence for

.pptx formats, XMLSlideShow, XSLFSlide, and XSLFTextShape classes need to be used.
.ppt formats, HSLFSlideShow, HSLFSlide, and HSLFTextParagraph classes need to be used.

Let us see the example of creating with .pptx format

Creation of a new presentation:

Next is adding a slide

Now, we can retrieve the XSLFSlideLayout and it has to be used while creating the new slide

Let us cover the whole concept by going through a sample maven project.

Example Maven Project

Project Structure:

As this is the maven project, let us see the necessary dependencies via pom.xml

" " ">

PowerPointHelper.java

In this file below operations are seen

A new presentation is created
New slides are added
save the presentation as

We can write Text, create hyperlinks, and add images. And also the creation of a list, and table are all possible. In general, we can create a full-fledged presentation easily as well can alter the presentation by adjusting the slides, deleting the slides, etc. Below code is self-explanatory and also added comments to get an understanding of it also.

We can able to get the presentation got created according to the code written and its contents are shown in the image below

We can test the same by means of the below test file as well

PowerPointIntegrationTest.java

Output of JUnit:

We have seen the ways of creating of presentation, adding text, images, lists, etc to the presentation as well as altering the presentation as well. Apache POI API is a very useful and essential API that has to be used in software industries for working with the presentation.
