Example 10.2 does not list the triangle classifier program for which the TriangleTest class is designed. Write a class named Triangle that meets the requirements in Example 10.1. Then run the JUnit tests in TriangleTest. Develop the code incrementally. Run TriangleTest against each increment. Continue the process until all tests have passed.
