Java programs do not run by any platform independence funda, but by a virtual machine which allows the program to be a “write once run anywhere code”-as Java lovers call it.

The 25 Factorial in Java

Chinmoy — Wed, 04 Jun 2008 03:30:18 +0000

In Java, the factorial of large numbers can be easily implemented in SE6 using the bigInteger class. The logic is the same as for finding factorials. The code goes as follows:

import java.math.BigInteger;
import java.lang.*;
import java.util.Scanner;
class largenumber
{
public static void main(String args[])
{
Scanner in=new Scanner(System.in);
System.out.println("Enter a number for factorial");
int num=in.nextInt();
BigInteger fact=BigInteger.valueOf(1);
for(int i=2;i<=num;i++)
{
fact=fact.multiply(BigInteger.valueOf(i));
}
System.out.println("Factorial "+num+" is ::nt"+fact);
}
}
