Question

ADD CODE: MOVE ZOMBIE W/ ARROW KEYS CONTINUOUSLY. EX: IF IT IS UP, IT MUST CONTINUE UP EVEN W/ 1 CLICK UNLESS YOU CLICK ANOTHER ARROW KEY.

public class j extends java.applet.Applet implements Runnable {

Image z[] = new Image [2];

Image crImg;

Thread r;

int x;

int y;

public void init() {

String zSrc[] = {"z1.png", "z2.png",};

for (int i = 0; i < zombies.length; i++) {

z[i] = getImage(getCodeBase(), "images/" + zSrc[i]); }}

public void start() {

if (r == null) {

r = new Thread(this);

r.start();}}

public void stop() {

if (r != null) {

r.stop();

r = null;}

void pause (int time) {

try { Thread.sleep(time); }

catch (InterruptedException e) { }}

public void run() {

walk (0, size().width); }

void walk (int start, int end) {

for (int i = start; i < end; i += 1) {

x = i;

if (crImg == zombies[0])

crImg = zombies[1];

else crImg = zombies[0];

repaint();

pause(150);}

public void paint(Graphics g) {

if (crImg != null)

g.drawImage(crImg, x, y, width, height, this);}

Applet is an outdated technology.

import java.applet.*;  
import java.awt.*;  
import java.awt.event.*;  
public class EventApplet extends Applet implements ActionListener{  
Button b;  
TextField tf;  
  
public void init(){  
tf=new TextField();  
tf.setBounds(30,40,150,20);  
  
b=new Button("Click");  
b.setBounds(80,150,60,50);  
  
add(b);add(tf);  
b.addActionListener(this);  
  
setLayout(null);  
}  
  
 public void actionPerformed(ActionEvent e){  
  tf.setText("Welcome");  
 }   
}
