Why can't we add Windows and Frames to Frames when we can add Panels to Applets.And one more thing can an application extend Scrollpane or Window or Panel and can an Applet extend Panel.Somebody please explain me. Thanks a lot.
In my opinion you need to study the AWT in more depth. I think one should learn Java first and then try to go for Certification. In that order.
Is is stated in the Java language Spec that <CODE>Window</CODE> is a top-level <CODE>Container</CODE> and as such cannot be included in any other. By the dictates of OOP, all descendants of <CODE>Window</CODE>, being <CODE>Window</CODE>s themselves, will behave accordingly.
One must understand the "IS A" and "HAS A" OOP concepts.
