In this example, You learn about Factorial of Large Number in java program.
Here you learn factorial of large numbers in Java, You are given a number and the task of the program to find factorial of large number.
Factorial of Large Number Program in Java
import java.util.Scanner;
import java.math.BigInteger;
public class BigFactorial
{
public static void main(String args[])
{
int n, c;
BigInteger inc = new BigInteger("1");
BigInteger fact = new BigInteger("1");
Scanner input = new Scanner(System.in);
System.out.println("Input an integer");
n = input.nextInt();
for (c = 1; c <= n; c++) {
fact = fact.multiply(inc);
inc = inc.add(BigInteger.ONE);
}
System.out.println(n + "! = " + fact);
}
}
Input an integer 50 50! = 30414093201713378043612608166064768844377641568960512000000000000
