Java Fundamentals

Objective:
- To complete the method stubs in each of the provided classes
  - MathUtilities
  - PredicateUtilities
  - StringUtilities
Purpose:
- To establish familiarity with
Classes to be completed:
- MathUtilities
- PredicateUtilities
- StringUtilities
Instructions
- Complete each of the method stubs in the main classes provided.
  - main classes are located in src.main.java.com.zipcodewilmington.danny_do_better_exercises
- There are comments above each method stub to describe the expected behavior.
- Begin by first ensuring the main method in your ZipcodeRocks class prints "Zipcode Rocks!" upon execution.
- Upon completion, open and run the TestSuite class to ensure that all tests have 100% success.
  - TestSuite is located in src.test.java.com.zipcodewilmington.danny_do_better_exercises

Predicate Utilities

A predicate is a clause which states something about a subject. (e.g., is assigning in "Leon is assigning homework")
Ensure each of the test cases passes successfully in the class TestPredicateUtilities by completing each of the method stubs in the class PredicateUtilities.
Method Stubs to be completed
- boolean isGreaterThan(int x, int y)
- boolean isLessThan(int x, int y)
- boolean isGreaterThanOrEqualTo(int x, int y)
- boolean isLessThanOrEqualTo(int x, int y)

Ensure each of the test cases passes successfully in the class TestMathUtilities by completing each of the method stubs in the class MathUtilities.
