Created By: Geoffrey Challen

/ Version: 2020.11.0

Create a public class named BinaryTreeEvenSum with a single class method named evenSum. evenSum accepts a BinaryTree<Integer>, that is a BinaryTree containing Integer values. Return the sum of all of the even values in the tree.

For reference, cs125.trees.BinaryTree has the following public properties:

Test Design Challenge

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

• Provide a public class named TestBinaryTreeEvenSum 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
