(HELP)!!!!How to change this code to draw a rectangle?

Question

* File: DrawLines.java
* This program allows users to create lines on the graphics
* canvas by clicking and dragging with the mouse.
import acm.graphics.*;
import acm.program.*;
import java.awt.event.*;
/** This class allows users to draw lines on the canvas */
public class DrawLines extends GraphicsProgram
implements MouseListener, MouseMotionListener {
/** Private instance variables */
private GLine line;
/** Initializes the program by enabling the mouse listeners */
public void init() {
addMouseListeners();
/** Called on mouse press to create a new line */
public void mousePressed(MouseEvent e) {
/** when the left button is pressed, create a zero length line */
line = new GLine(e.getX(), e.getY(), e.getX(), e.getY());
add(line);
/** Called on mouse drag to reset the endpoint */
public void mouseDragged(MouseEvent e) {
/** and now drag that line across the canvas
* the line will stop automatically when we lift our
* finger from the mouse
line.setEndPoint(e.getX(), e.getY());
This is drawline programm, but I want to change it to rectangle, use setbounds.
Help!

h1. The Ubiquitous Newbie Tips
* DON'T SHOUT!!!
* Homework dumps will be flamed mercilessly.
* Have a quick scan through the [Forum FAQ's|http://wikis.sun.com/display/SunForums/Forums.sun.com+FAQ].
h5. Ask a good question
* Don't forget to actually ask a question. No, The subject line doesn't count.
* Ask once
    - Don't Crosspost!
    - Two people answering one question independantly is a waste of there time.
* Don't even talk to me until you've:
    (a) [googled it|http://www.google.com.au/] and
    (b) looked it up in [Sun's Java Tutorials|http://java.sun.com/docs/books/tutorial/] and
    (c) read the relevant section of the [API Docs|http://java.sun.com/javase/6/docs/api/index-files/index-1.html] and maybe even
    (d) referred to the JLS (for "advanced" questions).
* [Good questions|http://www.catb.org/~esr/faqs/smart-questions.html#intro] get better Answers. It's a fact. Trust me on this one.
    - Lots of regulars on these forums simply don't read badly written questions. It's just too frustrating.
      - FFS spare us the SMS and L33t speak! Pull your pants up, and get a hair cut!
    - Often you discover your own mistake whilst forming a "Good question".
    - Many of the regulars on these forums will bend over backwards to help with a "Good question",
      especially to a nuggetty problem, because they're interested in the answer.
* Improve your chances of getting laid tonight by writing an SSCCE
    - For you normal people, That's a: Short Self-Contained Compilable Example.
    - Short is sweet: No-one wants to wade through 5000 lines to find your syntax errors!
    - Often you discover your own mistake whilst writing an SSCCE.
    - Solving your own problem yields a sense of accomplishment ;-)
h5. Formatting Matters
* Post your code between a pair of {code} tags
    - That is: {code} ... your code goes here ... {code}
    - This makes your code easier to read by preserving whitespace and highlighting java syntax.
    - Copy&paste your source code directly from your editor. The forum editor basically sucks.
    - The forums tabwidth is 8, as per [the java coding conventions|http://java.sun.com/docs/codeconv/].
      - Indents will go jagged if your tabwidth!=8 and you've mixed tabs and spaces.
      - Lines longer than 80 characters should be wrapped.
      - Proper indentation illustrates program logic.
* Post your error messages between a pair of {code} tags:
    - That is: {code} ... errors here ... {code}
    - To make it easier for us to find, Mark the erroneous line(s) in your source-code. For example:
        System.out.println("Your momma!); // <<<< ERROR 1
    - Note that error messages are rendered basically useless if the code has been
      modified AT ALL since the error message was produced.
    - Here's [How to read a stacktrace|http://www.0xcafefeed.com/2004/06/of-thread-dumps-and-stack-traces/].
* The forum editor has a "Preview" pane. Use it.
    - If you're new around here you'll probably find the "Rich Text" view is easier to use.
    - WARNING: Swapping from "Plain Text" view to "Rich Text" scrambles the markup!

If you (the newbie) have covered these bases *you deserve, and can therefore expect, GOOD answers!*
h1. The pledge!
We the New To Java regulars do hereby pledge to refrain from flaming anybody, no matter how gumbyish the question, if the OP has demonstrably tried to cover these bases. The rest are fair game.
