Submit Rational.java & Counter.java

Compare the test cases from the RationalTest class with the ones you created in the pre-lab. Were there kinds of test cases that you did not consider? Were there kinds of test cases that you proposed that were not in the RationalTest class?

Compare the constructors and methods from the Counter class with the methods you proposed in the pre-lab. Were there methods that you did not consider? Were there methods you proposed that were not in the Counter class? Do expectations for the methods as expressed in the CounterTest class differ from what you expected? Can you justify your omissions and additions?

You probably used two private data fields (numerator and denominator) in the implementation of yourRational class, but there are other options. For example, we could have used three fields (sign, numerator, and denominator). In this case, both the numerator and denominator would be guaranteed to be positive and the sign field indicates whether the object is positive or negative. How would this have changed the implementation of the methods of the Rational class?

Come up with a new implementation of the Counter class that uses different data fields. How does this affect the methods of the class?

Implement and test equals and toString for the Rational class.

Think further about a class that would represent a bank account. Give responsibilities for it. List the data fields and any constraints. Give a list of methods with their pre-conditions, post-conditions, and test cases.

Think about a class that would represent a colored triangle that could be displayed on a computer screen. Give responsibilities for it. List the data fields and any constraints. Give a list of methods with their pre-conditions, post-conditions, and test cases.
