I have 2 windows opened in my Java swing program. If I close one window, the programs stops execution. Is there any way not to stop the execution and play with the other window? Please explain with a sample code as I am new to swings. I tried searching in web, but I think I am lacking proper keywords for this.

    You’re probably setting your new windows’ close operations to EXIT_ON_CLOSE. Look for places where this happens in your code:

    JFrame frame = ... ;
// ...
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    And replace EXIT_ON_CLOSE with DISPOSE_ON_CLOSE for all but the window that you want to have exit the application when closed.

    Also take a look at the other ON_CLOSE values that you can pass in the setDefaultCloseOperation javadocs.
