Hi gurus,
I am having a parent class(ParentWin), inside this i
will create an object of child class(ChildWin).
My requirements comes like if i create one more instance of parent class(ParentWin),child class should not be created.Once an object of child class(ChildWin)is created it should not be instantiated again..Can you please suggest for single instance
of childWin at any point of time...

ParentWin---- mainwindow
ChildWin ---- childwindow created
from main window.
So when i create one more instance of Parent window( 2nd instance) and try to create child window, the earlier created child window should be shown, so new creation should happen
advance thanks for Suggestions.
Thanks&Regards,
selva.

mmh, looks like you need to implement the singleton pattern... (and this has nothing to do with Swing/JFC/AWT)
have a look here:
GoF singleton pattern
Singleton in Java
your ChildWin will implement the singleton pattern, and when ParentWin wants to get a ChildWin, it will call the instance() method
