Some non-FRC programming help

So I'm working on a project for one of my classes and I'm using the ActionListener interface (Java). I need to make the button that appears on screen jump to a different location. The actionPerformed method is where I'm having an issue. I'm not sure what to do there. Any ideas? Thanks in advance!

public class JumpingButton extends JFrame implements ActionListener
{
    JButton button;
    public JumpingButton()
    {
	setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	getContentPane().setLayout(new GridLayout(1,1));

	button = new JButton("Click this!");
	getContentPane().add(button);
	pack();
	setVisible(true);

	button.addActionListener(this);
    }
    
    public void actionPerformed(ActionEvent e)
    {
	
    }

    public void relocate(JFrame f)
    {
	Random rand = new Random();
	/*If this function is called, it will relocate the window to a new random position on the screen*/
	Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
	Dimension windowSize = f.getSize();
	int x = rand.nextInt(screenSize.width - windowSize.width);
	int y = rand.nextInt(screenSize.height - windowSize.height);
	f.setLocation(x,y);
    }
}

Re: Some non-FRC programming help

So I got the button to jump, but now I need a counter and timer. I have some code to handle that, but it doesn't work. Any help would be greatly appreciated.

Code:
/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */

package assignment2;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.util.*;

/**
 *
 * @author tuc73318
 */
public class JumpingButton extends JFrame implements ActionListener
{
    JButton button;
    int timesClicked = 0;
    public JumpingButton()
    {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	getContentPane().setLayout(new GridLayout(1,1));

	button = new JButton("Click this!");
	getContentPane().add(button);
        button.setActionCommand("press");
	pack();
	setVisible(true);

	button.addActionListener(this);
    }
    
    public void actionPerformed(ActionEvent e)
    {
        timesClicked++;
        long startTime = System.currentTimeMillis();
        JFrame f = (JFrame) new JumpingButton();
	Random rand = new Random();
	/*If this function is called, it will relocate the window to a new random position on the screen*/
	Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
	Dimension windowSize = f.getSize();
	int x = rand.nextInt(screenSize.width - windowSize.width);
	int y = rand.nextInt(screenSize.height - windowSize.height);
	f.setLocation(x,y);
        if(timesClicked == 10)
        {
            long endTime = System.currentTimeMillis();
            long finalTime = (endTime - startTime)/(1000);
            System.out.println("Your score is: " + finalTime + "s!");
            System.exit(0);
        }
        
    }
}
