MouseListener isn't working right

[john price]

What is wrong with my code? The only thing that works (out of the MouseListener and KeyListener) is the MouseListener. Partially. It is printing out the System.out.println line. It is not doing anything else.

import java.awt.*;
import java.awt.Color.*;
import java.awt.event.*;
import java.awt.geom.*;

import javax.swing.*;
import javax.swing.Timer;

public class Ball extends JPanel implements ActionListener, MouseListener, KeyListener {

    //double instead of Double
    double q = 40.00;
    double w = 300.00;
    double t = 300.00;
    double z = 40.00;
    Timer timer;
    Boolean direction = false;
    Boolean start = false;

    public Ball() {
	this.setFocusable(true);
        timer = new Timer(20, this);
        timer.start();
	this.setBackground(Color.BLUE);
	this.addMouseListener(this); 
	this.addKeyListener(this);
    }
	public void mousePressed(MouseEvent me) { 
        	if (direction) {
		w -= 2.00;
		}
		else {
		w += 2.00;
		}
		repaint();
		System.out.println("works");
          	}
    public void mouseReleased(MouseEvent e) {
    }

    public void mouseEntered(MouseEvent e) {
    }

    public void mouseExited(MouseEvent e) {
    }

    public void mouseClicked(MouseEvent e) {
    }
	public void keyPressed(KeyEvent e) {
	switch(e.getKeyCode()) {
	case KeyEvent.VK_UP : System.out.println("up"); break;
	case KeyEvent.VK_DOWN : System.out.println("down"); break;
	}
	}
	public void keyTyped(KeyEvent e) {
	}
	public void keyReleased(KeyEvent e) {
	switch(e.getKeyCode()) {
	case KeyEvent.VK_UP : System.out.println("up"); break;
	case KeyEvent.VK_DOWN : System.out.println("down"); break;
	}
	}
    protected void paintComponent (Graphics g) {
        super.paintComponent(g);//removes all previously drawn content and draw from scratch
        Graphics2D g2 = (Graphics2D) g;
        Ellipse2D ellipse = new Ellipse2D.Double(w, t, q, z); //x, y, width, height
        g2.setColor(Color.RED);
        g2.fill(ellipse);
    }

    public void actionPerformed(ActionEvent ex) {
	if (start = false) {
	direction = true;
	start = true;
	}
	if (w <= 0) {
	direction = true;
	}
	else if (w >= 600 - q * 1.5) {
	direction = false;
	}
	if (direction) {
	w += 2.00;
	}
	else {
        w -= 2.00;
	}
        repaint();
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame();
        frame.setTitle("ball");
        frame.setSize(600, 600);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container contentPane = frame.getContentPane();
        contentPane.add(new Ball());
        frame.setVisible(true);
    }
}

No error message. I just was testing to see if it was working. I just added a System.out.println statement and it ran fine.

Please talk more about your problem so we can see that you understand
the code and what it is intended to do. We want to help but please don't
make us guess about your question.

Up and Down don't generate valid characters. You should be use keyPressed() not keyTyped().

Just figured that out, thanks. Could you help me with the other problem?

I found out it was working properly. I am sorry for the question.
