Monday - Wednesday (5/7/12 - 5/9/12)

• Methods & functions in Java
  1. Do you want the method/function to be usable by other files?
     • Yes - public
     • No - private
  2. static (just put it there)
  3. Do you want the method/function to return anything?
     • Yes - put the return type (e.g. int, double, String, etc.)
     • No - void
  4. What do you want the name of the method/function to be?
     • Must be all one word, no spaces (follows same rules as variable names)
  5. Do you want the method/function to have any input parameters?
     • No - just have empty parentheses
     • Yes - declare the variable parameters and their types in the parentheses
  • Example template: public/private static RETURNTYPE FUNCTIONNAME(PARAMETERS)
  • Example: public static int functionName(int x, int y)
• Java Functions Practice

1. int compare(int a, int b)
   • Define a compare(int a, int b) function that returns 1 if a > b, 0 if a == b, and -1 if a < b
   • Test your compare function with 3 different function calls:
     • compare(5, 4)
     • compare(7, 7)
     • compare(2, 3)
2. double hypotenuse(double a, double b)
   • Define a hypotenuse(double a, double b) function that returns the length of the hypotenuse of a right triangle given the lengths of legs a and b
   • Test your hypotenuse function with the following function calls:
     • hypotenuse(3, 4)
     • hypotenuse(12, 5)
     • hypotenuse(7, 24)
3. double f2c(double t)
   • Define a function named f2c(double t) that converts the temperature parameter t from Fahrenheit to Celsius and returns it.
   • If you don't remember the formula to convert, then look for it online!
   • Create your own function calls that test the function
4. double c2f(double t)
   • Define a function named c2f(double t) that converts the temperature parameter t from Celsius to Fahrenheit and returns it.
   • If you don't remember the formula to convert, then look for it online!
   • Create your own function calls that test the function
