JAVA Program to find factorial of a number

In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n:

For example:
6! = 6*5*4*3*2*1 = 720

Steps to be followed for finding the factorial of a number.

1. Input the number.
2. Initialise a variable fact=1;
3. Create a loop for 1 to Number
4. Multiply each value of loop to the fact.
5. Print the value of fact

Sounds Good ? Let's get started

CODE:

 * Question:Write a program to accept a number and print its factorial.
 */
import java.util.*;
public class MyClass {

    public static void main(String args[]) {
      Scanner sc=new Scanner(System.in);
      
      System.out.println("Enter the number");
      int n=sc.nextInt();
      int i,fact=1;
      for(i=1;i<=n;i++)
      {
          fact=fact*i;
      }
      System.out.println("Factorial of "+n+" is: "+fact);
      
    }
}

Output:

Example 1
Input: Enter the number
       5
Output: Factorial of 5 is 120

Example 2
Input: Enter the number
      4
Output: Factorial of 4 is 24
