Loop Options

The loop is a counting loop. Each iteration of the loop will draw one red circle when the loop body is filled in:

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

// assume that the drawing area is 300 by 150
public class tenCircles extends Applet
{
  final int width = 300, height = 150;

  public void paint ( Graphics gr )
  {
    int count = 0;

    while ( count < 10 )
    {


      count = count + 1;
    }

  }
}

There are many ways to fill in the blanks so the loop iterates 10 times, but usually it is best to have a counter that goes from 1 to 10, or from 0 to 9. Often arithmetic is easier when the loop counts from 0 to 9.

Now let us focus on drawing the circles. The idea is to draw 10 circles in a row, nicely spaced out across the screen.

FRAGE 11:

The applet's drawing area is 300 pixels wide. If there are to be 10 circles, how wide is the area which will be used for each circle?
