METHODS EXAMPLES

1. Identify the implicit and explicit parameters:

   System.out.println("Knock it off");
   String food = "pizza";
   food.length();
   pawn.isValidMove(chessBoard, destination);

2. Draw a picture of the following:

   int amtCopy = 0;
   int amtFood = food.length();
   amtFood = amtCopy;

3.a) Suppose the method convert() changes all uppercase letters in a 
     string to lowercase letters, but also returns the number of 
     characters changed.  What is n?

     n = convert("Today I visited Professor Smith");

  b) Suppose factorial() returns the factorial of its single, integer 
     explicit parameter.  What is m?

     m = factorial(4);

  c) What is j?

     j = factorial(convert("Today I visited Professor Smith"));

4. Suppose the PrintStream class has two methods: printStars(), which 
   prints a line of 80 asterisks, and printStars(numStars), which prints 
   a line of numStars asterisks.

   a) Schematically show what happens when my program contains:
      
      printStars(80);

   b) This is an example of?
