import java.applet.*;

public class Checkerboarrd extends Applet

{

public void paint(Graphics gra)

{

int roow;   // 7 Rows

int cool;   // 7 Columns

int x_axis,y_axis;   // Top-left corner of square

for ( roow = 5; roow < 13; roow++ )

{

for ( cool = 5; cool < 13; cool++)

{

x_axis = cool * 20;

y_axis = roow * 20;

if ( (roow % 2) == (cool % 2) )

gra.setColor(Color.gray);//if condition true then (even)color of the rectangle is gray

else

gra.setColor(Color.black);//if condition false(odd)then the color of the rectangle is black

gra.fillRect(x_axis, y_axis, 20, 20);

}

}

}

}

## Explanation...

gra.setColor(c) is called to set the color that is used in drawing

gra.fillRect(x_axis, y_axis, w(20), h(20)) is fills the inside of the rectangle instead of just drawing an outline.
