```drawOval( 100-50, 300-50, 2*50, 2*50 )
```

Of course the method would work if you did the arithmetic and put the results in the method call.

# Drawing Rectangles

To draw a rectangle, use the `drawRect()` method of the Graphics object. This method looks like:

```drawRect(int  x, int  y, int  width, int  height)
```

It draws the outline of a rectangle using the current pen color. The left and right edges of the rectangle are at x and x + width respectively. The top and bottom edges of the rectangle are at y and y + height respectively.

This method is also used to draw a square. This applet draws a rectangle around the entire drawing area, then puts another rectangle in the center.

```import java.swing.JApplet;
import java.awt.*;

// assume that the drawing area is 150 by 150
public class SquareAndRectangle extends JApplet
{
final int areaSide = 150 ;
final int width = 100, height = 50;

public void paint ( Graphics gr )
{
setBackground( Color.green );
gr.setColor( Color.blue );

// outline the drawing area
gr.drawRect( 0, 0, areaSide-1, areaSide-1 );

// draw interior rectangle.
gr.drawRect( areaSide/2 - width/2 ,
areaSide/2 - height/2, width, height );
}
}
```

Here is what it draws on your screen:

Not all browsers can run applets. If you see this, yours can not.

In drawing the outer square, the value 1 was subtracted from its width and height so that the edges would be inside the drawing area.

### QUESTION 16:

What do you suppose the following method does?

```setColor( Color.blue )
```
