CSCI 202 Homework 3


In this assignment you will program a Java class following the Java standards.

This homework is similar to Homework 2.

Due dates

This assignment must be submitted to the Moodle submission page for Homework 3 with the name by 11:00 PM on Thursday, 2 February.

Starting the assignment

Your program must be written for the homework3 package. You should use the Java class TestDriver to test your class.


Implement an ADT with a Java class name BingoLabel in the package homework3 to represent a label on a Bingo card. The rules for these labels can be found in the Wikipedia article about Bingo. The BingoLabel should have properties “letter” and “number”. In your BingoLabel class there should be appropriate mutator and accessor methods for these properties, appropriate constructors, and a nice toString method for the class.

The Wikipedia article explains the legal combinations of letters and numbers. You should familiarize yourself with the allow letters, numbers, and combinations of the two. (For example, B-17 is not a legal label for a square.)

Your class should throw the execption IllegalArgmentException when its methods are passed improper parameters; however, your setLetter method should accept both lower and upper case letters.
