Closing JFrame with button click [duplicate]

Answer 1

You will need a reference to the specific frame you want to close but assuming you have the reference dispose() should close the frame.

jButton1.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e)
    {
       frameToClose.dispose();
    }
});

Answer 2

It appears to me that you have two issues here. One is that JFrame does not have a close method, which has been addressed in the other answers.

The other is that you're having trouble referencing your JFrame. Within actionPerformed, super refers to ActionListener. To refer to the JFrame instance there, use MyExtendedJFrame.super instead (you should also be able to use MyExtendedJFrame.this, as I see no reason why you'd want to override the behaviour of dispose or setVisible).

Answer 3

You can use super.dispose() method which is more similar to close operation.

Answer 4

JButton b3 = new JButton("CLOSE");

b3.setBounds(50, 375, 250, 50);

b3.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e)
    {
        System.exit(0);
    }
});

Answer 5

You cat use setVisible () method of JFrame (and set visibility to false) or dispose () method which is more similar to close operation.
