java swing close window without exiting app

Question

I have a little frame where I ask user & password. This frame will be opened clicking over a button in a main window.

Then I have two buttons: ok and cancel.

Answer 1

You can do it in many ways but these two ways are most usable one
1. write this.setVisible(false) in inside implemented ActionListener
Or
2. write this.dispose() inside implemented ActionListener. Hope this will help you.
