Test Writing: Comparable Max

Created By: Geoffrey Challen

/ Version: 2020.10.0

On this homework problem you'll implement a completely generic version of an algorithm to find the maximum of an array. Unlike in the past, when our algorithm only worked for int[] or double[], this version will work on any objects that are comparable, specifically any object that implements the Comparable interface.

Create a public class named Max with a single class method named max. max should accept an array of objects that implement Comparable and return the maximum. Assert that the array is not null or empty.

As a reminder, compareTo returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Test Design Challenge

You're challenge is to write tests for this problem described above.

• Provide a public class named TestMax with a single non-private class method named test that accepts no arguments and does not return a value.
• If the implementation of the class described above is incorrect, your test method should throw an exception.
• If it is correct, do not throw an exception.
• You may want to use Java's assert method
