 ## Predicate Utilities
 * Ensure each of the test cases passes successfully in the class [TestPredicateUtilities](./src/test/java/com/zipcodewilmington/danny_do_better_exercises/TestPredicateUtilities.java) by completing each of the method stubs in the class [PredicateUtilities](./src/main/java/com/zipcodewilmington/danny_do_better_exercises/PredicateUtilities.java).
