How to close a frame on action event of a button from a different class?

Question

I have a designed a control-frame on 1 class which has jbutton components, I have coded like on action event of these components diff-diff frame get initialized.

For each frame there is a class. now when I press second jbutton from control-frame then have to close the frame (which has opened when I pressed first jbutton from control-frame).

*"For each frame there is a class."* See [The Use of Multiple JFrames, Good/Bad Practice?](http://stackoverflow.com/a/9554657/418556) — Andrew Thompson, Mar 17 '13 at 00:19

Just keep track of frame instance as instance variable in main class. Then close that instance on clicking close button.

public void open(ActionEvent e) {
    frame = new  something.. // your frame
}

public void close(ActionEvent e) {
    frame.dispose();
}

Note: JFrame frame is global variable.
