Netbeans GUI editor generating its own incomprehensible code
In Netbeans(older versions), there are two types of applications to choose from when you're starting a new project. Java Application and Java Desktop Application.
What are the differences between these two types?
EDIT :
In newer versions of Netbeans, the Java Desktop Application is gone and only Java Application is available. Does that mean they have converged the functionalities of those two types in to one?
Now I'm using Java Application to create programs with GUIs as described here. Is it the correct way to go about it regarding creating applications with UIs?
While the answers provided are all correct, I wish to add some details. The Java Desktop Application is more like a template for a Java Swing UI app. It provides the Main App, the Main View and the About Dialog by default. You can add all your UI components thru the Main View class.
Other than that it's quite similar to a regular Java App. Note that you can also create a Java Swing UI app by selecting the regular Java App template.
This is supported until NetBeans 7.0. Now its deprecated and developers are adviced to use the NetBeans platform to develop UI applications. But you can definitely continue to create Swing Apps if you'd wish.
