Java Program to Calculate Factorial of given Number ?

Previously we have discussed the Program for 

Java program to Check Year Is Leap Year or Not ?

Below Program is used to calculate Factorial of any Number . Factorial is denoted by n!, is the product of all positive integers less than or equal to n. For example, 5 ! = 5 × 4 × 3 × 2 × 1 = 120.

The above example is implemented through program.

import java.util.Scanner;

public class Factorial {

 public static void main(String[] args) {
 System.out.print("Enter Number For Factorial : ");
 Scanner sc=new Scanner(System.in);
 int num = sc.nextInt();
 int out =1;
 for(int j=1;j<=num;j++){
 out = out * j;
 }
 System.out.println("OUTPUT : "+out);
 }
}

Program Output :-

Enter Number For Factorial :
5
OUTPUT : 120
