      Installing

      Before you can program in Java you need to download and install a Java Development Kit (JDK) , such as the Standard Edition (JDK SE) from Oracle’s website.¹ Among other things, the JDK includes the Java compiler, the class libraries, and the virtual machine needed to run Java applications. Oracle’s download page also has a link to obtain Netbeans² bundled with a JDK. Netbeans is an Integrated Development Environment (IDE) that will make development in Java much easier. Alternatively, another free IDE you can use is Eclipse.³ If you don’t want to use any IDE at all, a regular text editor will work just fine.

      Creating a project

      If you decide to use an IDE (recommended), you need to create a project, which will manage the Java source files and other resources. If you prefer not to use an IDE, you can create an empty file with the .java extension—for example, MyApp.java—and open it in your text editor of choice.

      To create a project in Netbeans, click File ➤ New Project. In the dialog box select the Java Application project type under the Java category and click Next. In this dialog box set the project name to MyProject and the name of the main class to myproject.MyApp. Change the project’s location if you want and click Finish to generate the project. The project’s only file, MyApp.java, will then open up, containing some default code. You can go ahead and remove all of that code so that you start with an empty source
