How can a button work in the Netbeans GUI
I am using NetBeans GUI to create a form.The form has been created ,but the problem is that I am not able to apply any action on the button.
I just want the guidance that what should be applied so that the buttons perform the action.
Foreg: the Exit button should take the command
System.exit(0);
Problem is I am not getting why is it not taking the command.
Please guide.
