The completed applet is given below.
The only tricky thing is to get the details right for selecting the random integers you want.
// assume that the drawing area is 400 by 400
public class thousandCircles extends Applet
{
Circle circ = new Circle();
Random rand = new Random();
public void paint ( Graphics gr )
{
circ.setRadius( 5 );
circ.setColor( Color.red );
int count = 1;
while ( count <= 1000 )
{
int x = Math.abs( rand.nextInt() )% 400;
int y = Math.abs( rand.nextInt() )% 400;
circ.setPosition( x, y );
circ.draw( gr );
count = count + 1;
}
}
}
Here is what the applet draws:
