Closing jFrame after clicking JButton

Question

I have designed two JFrames in NetBeans.

When I click the "rules" button (i.e placed on JFrame1) then it opens a second JFrame (but JFrame2 opens over JFrame1's window, that's what I dont want). In the second JFrame there is a "close" button. But when I click this button, I want JFrame1 to be opened and it is working too, but JFrame2 is actually not closed and JFrame1 is appearing over JFrame2.

In short the main form is JFrame1. When I click the "rules" button from JFrame1 it opens JFrame2 over JFrame1, and in JFrame2 there is a "close" button when it gets clicked the main form (i.e JFrame1) is lauched but it is launched over JFrame2.

The scenerio is JFframe1 -> JFrame2 -> JFrame1

Now my question is after clicking the "rules" button, JFrame1 should be closed and JFrame2 displayed on the screen and vice versa.

Answer 1

Assuming your button has an actionListener, after clicking the "rules button" put in:

      JFrame1.dispose();  //Remove JFrame 1
      JFrame2.setVisible(true) //Show other frame

And then reverese them for the opposite reaction

Answer 2

Somethig like this should be on the constructor or method which create JFrame2:

btnCancel.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        //call another method in the same class which will close this Jframe
        CloseFrame();
    }
});

It's method which should close JFrame2

public void CloseFrame(){
    super.dispose();
}
