Draw a Chessboard in Java Applet

Given task is to draw a Chessboard in Java Applet

Approach:

1. Create a rectangle with length and breadth of 20 unit each, with 10 rows and columns of chess.
2. As soon as even position occurs in row and column change the color of a rectangle with BLACK, else it will be WHITE

Below is the implementation of the above approach: 

Applet Program:

Java

import java.applet.*;
import java.awt.*;
/*<applet code="Chess" width=600 height=600>
</applet>*/
// Extends Applet Class
public class Chess extends Applet {

    static int N = 10;

    // Use paint() method
    public void paint(Graphics g)
    {
        int x, y;
        for (int row = 0; row & lt; N; row++) {

            for (int col = 0; col & lt; N; col++) {

                // Set x coordinates of rectangle
                // by 20 times
                x = row * 20;

                // Set y coordinates of rectangle
                // by 20 times
                y = col * 20;

                // Check whether row and column
                // are in even position
                // If it is true set Black color
                if ((row % 2 == 0) == (col % 2 == 0))
                    g.setColor(Color.BLACK);
                else
                    g.setColor(Color.WHITE);

                // Create a rectangle with
                // length and breadth of 20
                g.fillRect(x, y, 20, 20);
            }
        }
    }
}

Output:

Note: To run the applet in command line use the following commands.

> javac Chess.java
> appletviewer Chess.java
