1. Write a Java program that will take an integer number (i.e. N ) as an input from the keyboard and show the factorial of N. (In mathematics, the factorial of a positive integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example, 5! = 5 X 4 X 3 X 2 X 1 = 120. The value of 0! is 1.)

- Rewrite the code using a method named as fact (int). The method will take an integer number as its argument and return the factorial of that number. Use METHOD to write this program.
