Answer:

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

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

Drawing Rectangles

import java.swing.JApplet; import java.awt.*;  // assume that the drawing expanse is 150 past 150 public grade SquareAndRectangle extends JApplet {   final int areaSide = 150 ;   final int width = 100, elevation = l;    public void paint ( Graphics gr )   {      gr.setColor( Colour.white );     gr.fillRect( 0, 0, 150, 150 );     gr.setColor( Colour.blue );      // outline the cartoon area     gr.drawRect( 0, 0, areaSide-1, areaSide-1 );       // draw interior rectangle.     gr.drawRect( areaSide/2 - width/2 ,          areaSide/2 - superlative/two, width, tiptop );     } }

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

drawRect(int  10, int  y,      int  width, int  height)

It draws the outline of a rectangle using the current pen colour. The left and right edges of the rectangle are at ten 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 describe a square. This applet draws a rectangle effectually the unabridged drawing area, and then puts some other rectangle in the eye.

Here is what it draws on your screen:

Non all browsers can run applets. If you encounter this, yours can not.

In drawing the outer square, the value 1 was subtracted from its width and height so that the edges would exist within the drawing expanse.
