Add code to the generated source file A source file contains code, written in the Java programming language, that you and other programmers can understand. As part of creating an IDE project, a skeleton source file will be automatically generated.
You will then modify the source file to add the "Hello World! Compile the source file into a. The instructions contained within this file are known as bytecodes. Run the program The IDE invokes the Java application launcher tool javawhich uses the Java virtual machine to run your application.
In the New Project wizard, expand the Java category and select Java Application as shown in the following figure: In the Name and Location page of the wizard, do the following as shown in the figure below: In the Create Main Class field, type helloworldapp. The project is created and opened in the IDE.
You should see the following components: The Projects window, which contains a tree view of the components of the project, including source files, libraries that your code depends on, and so on.
The Navigator window, which you can use to quickly navigate between elements within the selected class. To do this, choose Tools Java Platforms as shown in the following figure: You should now see this newly added platform: You should see a screen similar to the following: The IDE has therefore created a skeleton class for you.
You can add the "Hello World! Optionally, you can replace these four lines of generated code: Later sections of this tutorial explain the use and format of code comments.

You have successfully compiled your program! Errors are reported in the Output window as hyperlinked text. You double-click such a hyperlink to navigate to the source of an error. You can then fix the error and once again choose Run Build Project.
When you build the project, the bytecode file HelloWorldApp. Files window, showing the generated. Now that you have built the project, you can run your program.
The next figure shows what you should now see. The program prints "Hello World! After that, the lessons go deeper into core language features and provide many more examples. Although the rest of the tutorial does not give specific instructions about using the NetBeans IDE, you can easily use the IDE to write and run the sample code.
Once you have created a project in the IDE, you can add files to the project using the New File wizard. You might want to create separate IDE projects for sample applications that include more than one source file.This tutorial will help you writing your first Java program, typically a “hello world” one - your first step of the adventure into Java programming world.
