Hello everyone, I'm having some issues with my rock, paper, scissors JApplet program. Of course I have it "extends Applets" from the beginning of my class and I realized that this wasn't the same as JApplet. After I changed "Applet" to "JApplet", when I ran it, it doesn't look like of what I had before I changed it to "JApplet". When I have "Applet", everything looks fine. So I'm assuming I need to change something around within my code. Here is my code and please let me know as to what I need to change for the program.

import java.awt.*;
import java.applet.*;

public class RPS extends JApplet implements ActionListener

    private Button rockButton;
    private Button scissorsButton;
    private Button paperButton;
    private String buttonPressed = "";
    private int computerValue = -1;
    private int myValue;
    private int playerScore = 0;
    private int computerScore = 0;
    private int drawScore = 0;

	private Image img1;

    public void init()
    {

		loadImage();
		rockButton = new Button("Rock");
		scissorsButton = new Button("Scissors");

		add(paperButton);
		rockButton.addActionListener(this);

    }

    {

What I can see from the picture, is that you need to clear your screen on a repaint().

Two ideas:
- Call super.paint(g); in the first line of your paint method. This is the paint method of the super class, it might help.
- Call a clearRect(0,0,getWidth(), getHeight());. This clears the screen, and might do the job.

Let me know if it works.

Ahh, I see now. At first, I found out that I needed to have the Container variable for it as well as changing the "Button" to "JButton". So I had to change some stuff around in there and I thought that would work, but it was giving me the exception. But when you mentioned the super.paint(g), I've added that and it works! Here is what I have now:

import java.awt.*;
import java.awt.event.*;

	Container c;

    private int myValue;
    private int playerScore = 0;
    private int computerScore = 0;
    private int drawScore = 0;

	private Image img1;

    public void init()
    {
		c = getContentPane();
		loadImage();
		rockButton = new JButton("Rock");
		scissorsButton = new JButton("Scissors");
		paperButton = new JButton("Paper");
		c.add(rockButton);
		c.add(scissorsButton);
		c.add(paperButton);
		rockButton.addActionListener(this);
		scissorsButton.addActionListener(this);
		paperButton.addActionListener(this);

    }

    public void loadImage()
    {

		img1 = getToolkit().getImage(url);

	}

    }

    {
    	super.paint(g);

So far, everything is the same. Just some stuff I had to change around. Thanks for your help! I appreciate it! :)
