Multiple key pressing

Here is an example of both multiple key press and repeat delay ignore. It is a terrible example of animation. Do not us this animation loop in a game. It will flicker far too much.import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

public class Test extends JFrame implements Runnable {

boolean upPressed=false, downPressed=false, leftPressed=false, rightPressed=false;

public Test() {

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

addKeyListener(new KeyAdapter() {

public void keyPressed(KeyEvent ke) {

switch (ke.getKeyCode()) {

case KeyEvent.VK_UP: upPressed = true; break;

case KeyEvent.VK_DOWN: downPressed = true; break;

case KeyEvent.VK_LEFT: leftPressed = true; break;

case KeyEvent.VK_RIGHT: rightPressed = true; break;

}

}

public void keyReleased(KeyEvent ke) {

switch (ke.getKeyCode()) {

case KeyEvent.VK_UP: upPressed = false; break;

case KeyEvent.VK_DOWN: downPressed = false; break;

case KeyEvent.VK_LEFT: leftPressed = false; break;

case KeyEvent.VK_RIGHT: rightPressed = false; break;

}

}

});

setSize(250,250);

setVisible(true);

Thread timer = new Thread(this);

timer.start();

}

public static void main(String[] args) {

new Test();

}

public void run() {

while (true) {

repaint();

try { Thread.sleep(30);} catch (Exception e) {}

}

}

public void paint(Graphics g) {

g.setColor(Color.white);

g.fillRect(0,0,getWidth(), getHeight());

g.setColor(Color.black);

g.drawString("Up",40,40);

if (upPressed) g.drawString("Pressed",100,40);

g.drawString("Down",40,60);

if (downPressed) g.drawString("Pressed",100,60);

g.drawString("Left",40,80);

if (leftPressed) g.drawString("Pressed",100,80);

g.drawString("Right",40,100);

if (rightPressed) g.drawString("Pressed",100,100);

}

}
