I have one main JFrame and one secondary JFrame. Now i want to close one JFrame but when I close that JFrame the main JFrame also gets closed. But I don't want that to get closed, so how do I stop it in java?

    Relevant: [The Use of Multiple JFrames: Good or Bad Practice?](https://stackoverflow.com/questions/9554636/the-use-of-multiple-jframes-good-or-bad-practice) -TL;DR: It is bad practice and not user friendly. So instead of two `JFrame`s, depending on your use-case 1) use a modal `JDialog` to display intermediate information, or 2) use a `CardLayout` to switch between context in your `JFrame`. – maloomeister Nov 17 '21 at 08:12

    You probably should show your `close` methods. Maybe you have somewhere a `System.exit(..)`? – jmizv Nov 17 '21 at 08:12

    Pssst.. the secret lies in the default close operation used for the frames in the code not shown. But follow the advice of @maloomeister, since there never should *be* two frames. – Andrew Thompson Nov 17 '21 at 08:30

there's a function in JFrame called setDefaultCloseOperation(...)

You can do:

setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE) which will set the visibility of the secondary frame to false instead of exiting the program
