New classes can be created and added to your project after you build the initial application and project.
To begin creating a Java class, you will open the Create Java Class dialog. To open the dialog, in the Application Navigator, right-click the project and choose New . In the New Gallery, select General in the Categories tree and Java Class in the Items list, then click OK.
Then, in the Create Java Class dialog, you will specify the class name and the package name.
When you create a class in JDeveloper, the class is added to the active project. You can immediately begin editing the class file in the source editor.
