Need help on a Frame question... Posted: Oct 31, 2002 10:56 PM

I hope someone can help me out with this question...
- Define a class, called MyFrame, which implements a frame by extending the Frame superclass. Your class should contain a constructor, which creates the frame with a named title bar. In addition to this, include in your declaration a protected button b, a protected checkbox group cg, and a protected checkbox c.

Thanks...

Don't you need like a "main" or "(String args[])" to able to execute it?

If you are running an application, you need to either add a main method to it or call it from another class which has one. If running from an applet, no.

So if you are running as an application you add a main method:
public static void main(String[] args){
 
}


and of course finish the program.
