Question

5. (10 points) The factorial of a nonnegative integer n is written n! and is defined as follows. n 2) ..1 (for values of n greater than 1) nn (n-l) and n-# 1 (for n 0 or n-1) l. Write a program that reads a nonnegative integer and computes and prints its factoria

Answer 1

import java.util.*;
public class MyClass {
public static void main(String args[]) {
Scanner in=new Scanner(System.in);
System.out.println("Enter non negative integer: ");
int n=in.nextInt();
long f = 1;
for(int i = 1; i <= n; ++i)
{
// factorial = factorial * i;
f *= i;
}
System.out.println("Factorial is: "+f);
}
}

Enter non negative integer: 5 Factorial is: 120
