SumOrProduct.java

/*Sum or Product
Write a program that asks the user for a number N and a choice C. And then give them the possibility to choose between computing the sum and computing the product of all integers in the range 1 to N (both inclusive).
If C is equal to -
 1, then print the sum
 2, then print the product
 Any other number, then print warning (without the quotes)*/
