    /*Program name:
    *Date: 10/04/2012
    *Time Spent: 30 min
    *Program Purpose: Create a class that has methods to
    *perform each of the arithmetic operations on two
    *numbers.In main, prompt the user for the input of two
    *numbers. After storing the values call each of the four
    *methods that perform simple arithmetic operations.
    *Each method should accept two numbers as formal parameters.
    *The addition method should add the two numbers together
    *and display the sum with a descriptive statement. The return
    *type will be void. The subtraction method should subtract
    *the smaller from the larger and display the difference.
    *The multiplication method should multiply the two numbers
    *together and return the product to be displayed in main. The division method
    *should check for division by zero and if the second number
    *is zero return a string error message otherwise the method
    *should return a String that reports the quotient and modulus
    *along with descriptive labels. The string, error or report,
    *will be displayed in main.*/
