Thread: Help With Java Game Code

Can someone please tell me how to get my paddle to move!? The paddle is the JButton b2. Also is there a way I can randomize the direction the ball goes after it hits the paddle? Here is what I have so far.

import java.awt.*;
 
import javax.swing.*;
 
import java.awt.event.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
