Need help please...

[etiger]

I wrote a simple program. It suppose to run on applet. When I run, it says

" Applet not initialized" Please help me... Where is the problem??

//############ Applet Part

	import java.awt.*;
	import javax.swing.*;

	public class CarApp extends JApplet {
	  public CarApp() {
	    add(new CarControl());
	  }

	  public static void main(String[] args) {
		  CarApp applet = new CarApp();
	    JFrame frame = new JFrame();
	    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
	    frame.setTitle("Car App");
	    frame.add(applet, BorderLayout.CENTER);
	    frame.setSize(500, 500);
	    frame.setVisible(true);
	  }

What command are you using to execute your code?
I see a main() method in a JApplet. There is some confusion here.
Applets do not use a main() method. They have a set of methods that the browser/appletviewer calls.

As alread mentioned you are mixing java methods with applet methods. You can delete the constructor of CarApp and the main method with its content and replace the code with the following

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class CarControl extends JApplet {

	public void init() {
		this.add(new CarMove());
		this.setSize(500, 500);
	}

	class CarMove extends JPanel {
        // copy the code of CarMove here

So now java is able to run the applet because your code has the init() method. for more details follow this link: http://download.oracle.com/javase/tu...ts/applet.html
