ANSWERS FOR FINAL REVIEW QUESTIONS

1. A property is a procedure that gets or sets the value of a data member.

2. Compiler: Syntax errors that can be caught before even running the 
      program.  They are marked with a wavy underline in the IDE.
   Exception: Situations that cause the program to crash such as 
      division by zero or itrying to use an object before instantiating it.
   Logic: Errors that are not compiler errors and do not cause the program
      to crash, but that cause wrong answers in the program.

3. Advantage of Double: Allow decimal numbers, have a larger range than
                        an int.
   Advantage of Integer: Takes up less space than a Double, no problems
                        with round off errors.
