Java Program to find Factorial of Number

Problem Statement

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


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).

import java.util.Scanner;

public class Factorial 
	public static void main(String args[])
		int n, fact = 1;
		Scanner in = new Scanner(;
		System.out.println("Enter the value of n:");
		n = in.nextInt();
		for (int i = n; i>=1; i--)
			fact = fact * i;
		System.out.println("The factorial of "+n+" is "+fact);

The output of the Factorial Program in Java

Enter the value of n: 5

The factorial of 5 is 120
