Background The the factorial of an integer n is the peoduct of all numbers from 1 so n and is wriien So 5 5 4 3 21 120 By definition, 0 1. Specifications Write a program that asks the user for an integen Ife integer is greater than or equal to O. the program calculates the factorial of that number and prints that value. Ife number entered is negative, the program prints an enor message and quits. main Method The rnan method s4 create a Scanner object, ask the user for an-leger, and use the Scanner objoct to get a input from the user If the input is negative, an error message is printed. If the input is not negative, the main method should call the factorial method to get the factorial of the integer entered by the user. And print the value retuned by the factorial method factorial Method The factorial method must take an integer as its parameter and return an integer The method should calculate the factorial of the value and return it Output Your output should look something like this Please enter an integer greater than or equal to zero The factorial of 0 is 1 Please enter an integer greater than or egual to zero 1 The faetorial of 1 is 1 Please enter an integer greater than or equal to zero 6 The factorial of 6 is 720 Please enter an integer greater than or equal to zero -3 You cannot take the factorial of a negative number
