Creatingpackages, the IDE will understand that we wish to create a package under the current one and will then automatically append the full path of the packages in Package Name. The user then needs to only type the rest of the path. This saves a lot of time when the project grows and nested packages start to spread. 23 Basic IDE Usage The second option is to right-click directly on the desired node in the Packages tab. In our example we are creating a package under Test Packages. Right-clicking on the Test Packages node will trigger a clean Package Name and it is up to the developer to decide what the full path is going to be.

Java: As seen in most Windows applications. It is implemented to give some information about the company, developer, and the version of application. java: The application launcher. Basically it is used to initialize resources, inject them into the desktop app, and run the GUI class, in our case, DesktopView. This is where the main method exists. java: Our main graphical class. This is where we will lay out the components, program those components to react to events, and so on. Note that these classes have different icons.

With this specific type of project, the Main class, the one created by NetBeans, is the one to execute. It is possible to run the main project by right-clicking on the project name and selecting Run or pressing F6. 26 Chapter 2 Debugging a class It is possible to set breakpoints and watches in NetBeans and, on execution, check what the value of a given variable or object is. NetBeans debugger also lets the developer follow method calls and execute code one line at a time giving a fine-grained visualization on how the code is running.
