COMP 170 Lab 8

Goals for this lab:

Gain experience with an interface:
Write and use classes implementing an interface

Setup

1. Download lab8files.zip, open the archive, and extract the files to a directory of your choice, and open it in BlueJ.

2. Look at the Game interface. Then look at AdditionGame, that implements the interface. It uses two new clearly named List methods remove and isEmpty. See how a new AdditionGame can be added to list of Games. Run Lab8's main method. Randomly choosing a game when there is only one to choose from is pretty silly, but it gives you a start on a more elaborate list of games.

3. Write several very simple classes implementing the Game interface, and modify the main method in Lab8 to create and add a new game of each type. (Test adding one at a time.)

One such game to create with little more work would be a variation on Guessing Game, adapting Assignment 3 so there is a GuessingGame object with a play method rather than static methods. You could make the maximum number be a parameter in the constructor.

4. Show the TA when you are done.
