BankAdmin Class

The BankAdmin class, which creates the user interface, is a Swing class that provides action methods that are called when certain events occur in the application, and methods that call the controller session beans. It was created using the NetBeans IDE Swing editor, Matisse.

Note –

Although BankAdmin was written using NetBeans IDE, you do not need to have NetBeans installed in order to run the application. If you want to alter the user interface, however, you do need to use NetBeans IDE.

The initComponents method is automatically generated by NetBeans IDE. It creates all the user interface elements visible in BankAdmin.
