Instructions:

1. Fork this Repository
   • fork this repository to your personal github account
   • clone 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.

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 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)

Math Utilities

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

String Utilities

• Ensure each of the test cases passes successfully in the class StringUtilitiesTest by completing each of the method stubs in the class StringUtilities.
• Method Stubs to be completed
  • String concatenation(String, String)
