To System.exit or not System.exit

[Myke3D]

How can i close a jframe without System.exit? I try but now methods come up.

[Myke3D]

I mean no methods. None.

Well, you can set the default close operation for the JFrame to DISPOSE_ON_CLOSE or you can use myJFrame.dispose() where myJFrame is your JFrame

If you are just closing the JFrame with the exit button on the top right corner,

If your class is just extending JFrame, add "this.setDefaultCloseOperation(EXIT_ON_CLOSE) ;

If the JFrame is an instance variable in your class, add "<variablename>.setDefaultCloseOperation(JFra me.EXIT_ON_CLOSE);

Just to clarify, add that line to the method where you initialize the frame, preferably before you set it to visible.

That will do the same thing as System.exit();

Of course it does, but the topic starter wanted to know how to exit a JFrame without using System.exit().

He wanted to know how to close a JFrame, much difference from exiting the application. Unless you are better at reading between the lines and interpreting what the author really means, I believe he just wants to close a JFrame, not exit the application.

That was a bad assumption on my part.
