+# Java Fundamentals
+* Classes to be completed
+	* MathUtilities
+	* PredicateUtilities
+	* StringUtilities
+
+## Predicate Utilities
+* Ensure that each of the test cases 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).
+* A _predicate_ is a clause which states something about a subject. (_e.g., **is assigning**_ in _"Leon **is assigning** homework"_)
+
+* 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)`
+
+
+## Math Utilities
+* Ensure each of the test cases in the class [TestMathUtilities](./src/test/java/com/zipcodewilmington/danny_do_better_exercises/TestMathUtilities.java) by completing each of the method stubs in the class [MathUtilities](./src/main/java/com/zipcodewilmington/danny_do_better_exercises/MathUtilities.java).
+* Method Stubs to be completed	
+	* `Integer add(int, int)`
+	* `Long add(long, long)`
+	* `Short add(short, short)`
+	* `Byte add(byte, byte)`
+	* `Float add(float, float)`
+	* `Double add(double, double)`
+	* `Integer subtract(int, int)`
+	* `Long subtract(long, long)`
+	* `Short subtract(short, short)`
+	* `Byte subtract(byte, byte)`
+	* `Float subtract(float, float)`
+	* `Double subtract(double, double)`
+	* `Integer divide(int, int)`
+	* `Long divide(long, long)`
+	* `Short divide(short, short)`
+	* `Byte divide(byte, byte)`
+	* `Float divide(float, float)`
+	* `Double divide(double, double)`
+	* `Integer multiply(int, int)`
+	* `Long multiply(long, long)`
+	* `Short multiply(short, short)`
+	* `Byte multiply(byte, byte)`
+	* `Float multiply(float, float)`
+	* `Double multiply(double, double)`
+	* `Boolean returnTrue`
+	* `Boolean returnFalse`
+
+
+## String Utilities
+* Ensure each of the test cases in the class [TestStringUtilities](./src/test/java/com/zipcodewilmington/danny_do_better_exercises/TestStringUtilities.java) by completing each of the method stubs in the class [StringUtilities](./src/main/java/com/zipcodewilmington/danny_do_better_exercises/StringUtilities.java).
+* Method Stubs to be completed
+	* `String concatenation(String, String)`
+	* `String concatenation(int, String)`
+	* `String getPrefix(String)`
+	* `String getSuffix(String)`
+	* `String compareTwoStrings(String)`
+	* `Character getMiddleCharacter(String)`
+	* `String getFirstWord(String)`
+	* `String getSecondWord(String)`
+	* `String reverseTheTwo(String)`
