//1. no-argument Constructor:
//Assign your name to name, course, and school to name,
// course, and school
//Assign the system's date to dateCreated

//product 5, $7.87, and product 6, 99.9.
//
//The method calculateSales accepts two arguments for product number
//and quantity sold.
//Use a swicth statement to determine and return the retail price for the product.
//For example, if method receives 2 and 10, it should return 55.00.
//The method return 0 for invalid product number.

//
//The method reverseDigits accepts a single argument of type integer.
//The method takes an integer value and returns the number with its digits
//reversed. For example, given the number 7631, the method should return 1367.
