 Programming Process:
 1. Understand problem
 2. Develop and algorithm (use pseudocode)
 3. Code in Java
 4. Debug
 5. Test --
 Put together datasets for which the program behaves differently.
 Try each data set, sometimes this is called a "test suite"
 We can also call the method inside of a loop to test it on many
 different values.
