closing multiple JFrames

I have JFrame1 that contains a button. This button when clicked creates multiples of JFrames, a minimum of 3. However, I wanted to add a button that will close those JFrames i opened..

# 1

then your code needs to keep a track of all those jframes

You mean I should remember all those JFrame objects? what is the method that closes JFrame aside from setDefaultCloseOperation?.Big Thanks!!

setVisible(false) then stop referring to the object. it'll get GC'd (probably)

setVisible(false) or dispose() ... or hide() [which is deprecated]

hmmmm, a new concept to me.. I'll research about it. The application creates those frames inside a looping statement, is it possible to map that. Thanks

Note that setVisible(false) only hides the frame (and afterwards it can be set visible again), whereas dispose() releases all resources used by that frame as well (and it cannot be restored). The method setDefaultCloseOperation(int) only sets the action taken when the user clicks on the x that closes a window.
