this doesn't really involve codes but....
i have a problem in using my netbeans...i'm still new to this program and i don't know the controls and menus...I made buttons/JButtons but I don't know what to do next. I want that when I click a button, another lists or box will appear, how will I make another one? what will I click in the menus?
hope you can help me...thank you!
When you've made a button, or any other element, you can attach an event listener to that element, by right-clicking the element you've made (e.g. button), and you can choose what kind of event listener you want to attach.
Then netbeans will automatically generate a method (event handler) associated with the element that you just attach an event listener to. You can write the code you want in that event handler, such as making a new button appear .
Consult The Java Tutorial for more info on event listener.
