Lab 3

Lab Partners

Everyone should work with one lab partner on this assignment.

Objectives

The goals of this lab are to help you (1) see what your classmates were able to do with the Battleship assignment and (2) become acquainted with the MouseListener interface and MouseAdapter class.

Part I: Battleship Evaluation

At the start of the lab, make your Battleship program available on an unused computer near where you are sitting. During the course of the lab, find five Battleship programs other than your own. With each program, play it twice and then quit. You do not need to look at the underlying code.

Grading: 5 points

For each of the five programs that you play, write down the following. Each evaluation is worth 1 point.

• The author(s) of the program.
• On a scale of 0 - 10 where 0 means "not working", 5 means "ok" and 10 means "terrific", give this program a rating.
• What functionality is missing from the program?
• What visual aspects of the program can be improved?
• What is your favorite aspect of the program?
• Write down the high level GUI approach that the authors used. For example, a JPanel containing an 8 by 8 GridLayout of JButtons is placed on a JFrame. Feel free to talk to the authors to find out this information.

Part II: MouseListener

Take the lecture code that was finalized on Monday, January 30th and copy it into a BlueJ project named Lab3.

Modify the code so that in addition to its current functionality, it also keeps track of every spot where the mouse is clicked. In each spot where the mouse was ever clicked, a 10 by 10 yellow circle should be drawn.

Grading: 5 points

• The yellow circles are drawn correctly. 2 points.
• The black "+" signs are still drawn correctly. 1 point.
• An ArrayList is used to store all of the locations where a yellow circle should be drawn. 1 point.
• The MouseAdapter class is used. 1 point.

What to Submit

E-mail your final code and Battleship evaluation to your lab TA in one message with the following subject: CS 221-xx inlab3 name1, name2. The xx is the number of your lab section.

Before You Leave

Delete the BlueJ project that you created. Empty the recycle bin. Thank you.
