# Java Fundamentals

### **Objective:**
* To complete the method stubs in each of the provided classes
	* `MathUtilities`
	* `PredicateUtilities`
	* `StringUtilities`

### **Purpose:**
* To establish familiarity with
    * [primitive data-types](http://cs.fit.edu/~ryan/java/language/java-data.html)
    * [method signatures and return statements](http://www.homeandlearn.co.uk/java/java_methods.html)
    * [String operations](https://www.tutorialspoint.com/java/java_strings.htm)
    
### **Classes to be completed:**
* `MathUtilities`
* `PredicateUtilities`
* `StringUtilities`
	
### **Instructions:**

1. Fork this Repository
    * [fork](https://help.github.com/articles/fork-a-repo/) this repository to your personal github account 
    * [clone](https://help.github.com/articles/cloning-a-repository/) **your** `forked` repository to your local machine.
    * Complete steps 2 and 3  
    * `git add` your changes to the list of your `commited` files.
    * `git commit` your added files to the list of your `staged` files.
    * `git push` your staged files to your remote repository.
    * submit a `pull request` which compares Zipcoder `master` to your `master`.
2. Complete each of the method stubs in each of the `main` classes provided.
    * There are comments above each method stub to describe the expected behavior.
3. Make sure you Run Tests


## 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 [PredicateUtilitiesTest](https://git.zipcode.rocks/ZipCodeWilmington/ZCW-Lab-Fundamental-Methods/src/branch/master/Method%20Fundamentals/PredicateUtilitiesTest.java) by completing each of the method stubs in the class [PredicateUtilities](https://git.zipcode.rocks/ZipCodeWilmington/ZCW-Lab-Fundamental-Methods/src/branch/master/Method%20Fundamentals/PredicateUtilities.java).
* 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
