Thread: Ping Pong Game Problem with ball Drop and Catch

I have created this ping pong game but having problem with ball and paddle collusion. After first collusion it gives score 1 but later it never touch the paddle.
Can anyone help with the code:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.geom.*;
import java.util.Random.*;
import javax.swing.ImageIcon;
 
public class Ball extends JFrame implements ActionListener, KeyListener{
	int xSpeed=0;
	int x,y;
	int x1,y1;
	int score;
	int randomNum;
    Rectangle blockRect;
    Rectangle ballRect;
	Timer time;
	public Ball(String title){
		super(title);
		xSpeed=5;
		x=400;
		y=100;
		x1= 325;
		y1= 500;
		time=new Timer(100,this);
		time.start();
		blockRect = new Rectangle(x1,y1,150,70);
		addKeyListener(this);
		setSize(800,600);
		setVisible(true);
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	}
	public void actionPerformed(ActionEvent e){
		y=y+xSpeed;
		repaint();
		if(y> this.getWidth()){
			y=25;
			score -=1;
		}
		if(blockRect.intersects(ballRect)){
			y=40;
			score +=1;
			x =200;
			y = 300;
		}
	}
	public void paint(Graphics g){
		Graphics2D g2d=(Graphics2D) g;
		Rectangle rect=new Rectangle(0,0,800,600);
		g2d.setColor(Color.BLACK);
		g2d.fill(rect);
		g2d.setColor(Color.CYAN);
		g2d.fillOval(x,y,25,25);
		ballRect=new Rectangle(x,y,30,30);
		g2d.setColor(Color.RED);
		g2d.fillRect(x1,y1,150,40);
		g2d.drawString("Score:" +score,500,50);
	}
    public void left() {
        x1-=5;
    }
    public void right() {
        x1 +=5;;
    }
    public void keyReleased(KeyEvent e)
    	{}
    public void keyTyped(KeyEvent e)
    	{}
    public void keyPressed(KeyEvent e)
    	{
        if (e.getKeyCode()==KeyEvent.VK_LEFT){
        	left();
        	System.out.println("Left:"+x1);
        }
        if (e.getKeyCode()==KeyEvent.VK_RIGHT){
        	  right();
        	  System.out.println("Left:"+x1);
        }
    }
	public static void main(String args[]){
		new Ball("Animated Ball");
	}
}

--- Update ---

I think something is wrong here:

public void actionPerformed(ActionEvent e){
y=y+xSpeed;
repaint();
if(y> this.getWidth()){
y=25;
score -=1;
}
if(blockRect.intersects(ballRect)){
y=40;
score +=1;
x =200;
y = 300;
}

A general architecture comment:

Don't draw directly on the JFrame by overriding its paint() method. That is not how painting in Swing is intended to be done. Instead, add a JPanel to the JFrame and draw on the JPanel using its paintComponent() method.

As for your question, perhaps its the placement of your repaint() call, though I'm not sure I understand what you're asking.

can anyone re-write the code I made mistake. I am trying to figure it out for many days without luck.
