So to get practice writing applets, I tried to write one that simply draws a chessboard in a 160 x 160 window. I am pretty sure I got the code right for both the html and java files, and I have the html file in the same directory as my java class file. However, when I attempt to open the html file in IE, it says "Loading Java Applet failed..." at the bottom left of the screen. Anything I can do?

java file code:

package drawchessboard;

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

//this class is written to draw a chessboard in a 160p x 160p applet window

public class Main extends Applet
{
    public void paint(Graphics g)
    {
        int startx=0, starty=0, endx=20, endy=20;
        for(int j=0;j<4;j++)//draws 2 rows
        {
            for(int i=0;i<4;i++) //draws a row starting with a white square
            {
                g.setColor(Color.white);
                g.fillRect(startx, starty, endx, endy); //draw white square 20x20
                startx+=20; //move one 20x20 square over
                endx+=20;
                g.setColor(Color.black);
                g.fillRect(startx, starty, endx, endy); //draw black 20x20 square
                startx+=20; //move one 20x20 square over
                endx+=20;
            }
            starty+=20; //move 20 pixels down
            endy+=20;
            for(int q=0;q<4;q++)
            {
                g.setColor(Color.black);
                g.fillRect(startx, starty, endx, endy); //draw black square 20x20
                startx+=20; //move one 20x20 square over
                endx+=20;
                g.setColor(Color.white);
                g.fillRect(startx, starty, endx, endy); //draw white 20x20 square
                startx+=20; //move one 20x20 square over
                endx+=20;
            }
            starty+=20; //move 20 pixels down
            endy+=20;
        }
    }
}

html file code:

<applet code="Main.class" width=160 height=160>
</applet>

Please open the browser's Java console, copy the contents and paste it here.

Remove the package statement or change the <APPLET code= to include the package name and move the html to the folder with the drawboard folder in it. Ie up one level.

The applet code doesn't have any of the methods that browsers call for communication:
init(), start, stop etc.

Thanks, moving it up one level worked...I didn't think about the package
