public class DirectionPanel extends JPanel

{

private final int WIDTH = 300,

HEIGHT = 200;

private final int JUMP = 10;

private final int IMAGE_SIZE = 31;

private ImageIcon up, down, right, left, currentImage;

private int x, y;

public DirectionPanel()

{

addKeyListener (new DirectionListener());

x = WIDTH / 2;

y = HEIGHT / 2;

up = new ImageIcon ("arrowUp.gif");

down = new ImageIcon ("arrowDown.gif");

left = new ImageIcon ("arrowLeft.gif");

right = new ImageIcon ("arrowRight.gif");

currentImage = right;

setBackground (Color.white);

setPreferredSize (new Dimension(WIDTH, HEIGHT));

setFocusable(true);

}

public void paintComponent (Graphics page)

{

super.paintComponent (page);

currentImage.paintIcon (this, page, x, y);

}

private class DirectionListener implements KeyListener

{

public void keyPressed (KeyEvent event)

{

switch (event.getKeyCode() ) //Virtual key codes are used to report which keyboard key has been pressed, rather than a character generated by the combination of one or more keystrokes//

{

case KeyEvent.VK_UP:

currentImage = up;

y -= JUMP;

break;

case KeyEvent.VK_DOWN:

currentImage = down;

y += JUMP;

break;

case KeyEvent.VK_LEFT:

currentImage = left;

x -= JUMP;

break;

case KeyEvent.VK_RIGHT:

currentImage = right; x += JUMP;

break;

}

repaint();

}

public void keyTyped (KeyEvent event) {}

public void keyReleased (KeyEvent event) {}

}

}

import javax.swing.JFrame;

public class Direction

{

public static void main (String[] args)

{

JFrame frame = new JFrame ("Direction");

frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

frame.getContentPane().add (new DirectionPanel());

frame.pack();

frame.setVisible(true);

}

}

A key event is generated when a keyboard key is pressed. Key events allow a program to respond immediately to the user while we r typing or pressing other keyboard keys such as the arrow keys. If key events are being processed, the program can respond as soon as the key is pressed; there is no need to wait for the Enter key to be pressed or for some other component (like a button) to be activated. The Direction program responds to key events. An image of an arrow is displayed, and the image moves across the screen as the arrow keys are pressed. Actually, four different images are used, one each for the arrow pointing in each of the primary directions (up, down, right, and left).
