You can use `yourFrame.setVisible(false);`. Have a look [here](http://stackoverflow.com/questions/1234912/how-to-programmatically-close-a-jframe) — x80486, Apr 09 '15 at 18:26

Use Frame.setVisible(false); if you're going to show that JFrame again, or Frame.dispose(); if you're done with it.

   public void actionPerformed(ActionEvent e)
     {
        frame.dispose(); // dispose the old frame
        JFrame frame1 = new JFrame("Project Format Creator");
        frame1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame1.setSize(300,300);//int width int height
        frame1.getContentPane().add(panel);
        frame1.setVisible(true);
     }
