## Write a Java Program to find Factorial of Number – Java Tutorial

### Problem Statement

** **Write a Java program to find the factorial of a number ‘n’ using for loop.

## Solution:

First, create a main class named Factorial. Then add the main method to the main class Factorial.

Declare local variables such as n – to store the value of a number, fact = 1 (Initial factorial values).

Create an object of the scanner class and read a number using the scanner class object and the nextInt() method.

Next loop over from n to 1 and multiply n to partial; factorial in every iteration.

Finally, display the result (factorial of number).

### The output of the Factorial Program in Java

Enter the value of n: 5

The factorial of 5 is 120
