Solution 1: Factorial Calculation using Loops Code: import java.util.Scanner; public class FactorialUsingLoop { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Taking user
Calculation: 4! = 4 * 3 * 2 * 1 = 24 Example Scenario 2: Input: int n = 0; Output: res = 1 Factorial of 0 is always 1. Finding Factorial using Iteration In the iterative approach, we use a loop like for or while to multiply the numbers in descending order to get the facto...
Although the calculation was 4*3*2*1 the final result is the same as before. Now let's take a look at how to calculate the factorial using a recursive method. Calculating Factorial Using Recursion A recursive method is a method that calls itself and terminates the call given some condition...
How to use BigInteger class in Java Here is our sample Java program to calculate large factorials. You will useBigInteger class to hold the result of the calculation. Remember this class is not insidejava.lang package,hence you need to explicitly import it, as we have done in this example....
