Write a program to print factorial of any number

import java.util.*;
class factorial
public static void main (String arg[])
Scanner in = new Scanner (;

int a,b=1;
System.out.print ("\n\t Enter the number = ");

while (a>0)

System.out.println ("\n\t Factorial = "+b);


     First of all computer will check the condition of while loop. If it is true then it will
 multiply b by a. After that it will decrease the value of a by 1 and repeat the same task. This
 will continue until a=0. When a=0 the loop will be broken and the next statement to it will
be executed.
