Introducing Factorial

Factorial is a the multiplication process of numbers reduced one by one until multiplied by one. Example 5! = 5 * 4 * 3 * 2 * 1 = 120. So the factorial of 5 is 120.

Factorial Class

This class included a fac method for processing factorial program.
public class Factorial { static int fac(int n) { if (n == 0) { //For factorial 0 is 1// return 1; } else { return (n * fac(n - 1)); } }

Main Method

This main method is used for executing factorial program
public static void main(String args[]) { int fact = 1; int number = 6;//It is the number to calculate factorial fact = fac(number); System.out.println("Factorial of " + number + " is: " + fact); } } //End of Class//
