Explanation / Answer

import java.awt.*;

import jpb.*;

public class Checkerboard {

public static void main (String[] args) {

DrawableFrame df = new DrawableFrame("Checkerboard");

df.show();

df.setSize(200, 200);

Graphics g = df.getGraphicsContext();

int counter=1;
for (int i=0; i<1600; i++)
{
int j=1; int x=0;
if (counter>=9)
{
x+=24;
}
if(i>=200)
{
i=0;
}
if ((i + j) % 2 != 0)
{

//Use setColor and fillRect methods to
   //fill the specified colors in rectangular
      //boxes
g.setColor(Color.voilet);
g.fillRect(i, x, 20, 20);
i+=24;
}
else
{
g.setColor(Color.yellow);
g.fillRect(i, x, 20, 20);
i+=24;
}
counter++;
}

df.repaint();

}
