Modularizing the Input Routine Functionality
- make an object when you see a common task repeated over and over
  - versus cutting and pasting code from other files
    - lowest form of code reuse
    - very error-prone
  - capture common task into class
  - use instance of class to carry out common task
- noninstantiable classes
  - can't make an instance of them
  - not as essential as instantiable
  - not that bad to just define it as instantiable
- method overloading implementation technique better than duplication
  - have one method call another version
  - return the value returned by the other version

Quick Check
1. InputHandler ih = new InputHandler();
   int age = input.getInteger("How old are you? ");
2. The getString method returns a string, which we then try to assign to an integer.  This causes a type mismatch error.
