Test Writing: OurComparable Max

Created By: Geoffrey Challen
/ Version: 2021.3.0

Create a public class named Max with a single class method named max. max should accept an array of objects that implement OurComparable 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 passed object. OurComparable works exactly the same as the official Comparable interface, except it is slightly simplified and does not accept a type parameter.

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
