Factorial Solver in Java

I wrote this program to ask the user to give the number and then the program will compute the factorial value of the given number using Java programming language.

import java.util.Scanner;


public class FactorialSolver {

/**

public static void main(String[] args) {
// TODO Auto-generated method stub
int number=0;
Scanner Input = new Scanner(System.in);

System.out.println("\n");
System.out.print("\tFactorial Solver in Java");
System.out.println("\n");
System.out.print("\tGive a Number : ");
number = Input.nextInt();
int factorial = number;
for (int i=(number -1); i > 1; i--){
factorial*=i;
}
System.out.println("\n");
System.out.print("\tFactorial of " + number + " is "+ factorial +".");
System.out.println("\n");
System.out.println("\tEnd of Program");
}
