easy method Find Binomial Coefficient using Factorial Function Java Programming Code

public class BinomialCoefficient {

    public static int factorial(int n) {

        int f = 1;

        for (int i = 1; i <= n; i++) {

            f = f * i;

        }

        return f; // factorial of n.

    }

    public static void main(String[] args) {

        int n = 5, r = 2;

        int nmr = n - r;

        int factN = factorial(n);

        int factR = factorial(r);

        int factNMR = factorial(nmr);

        int BinCo = factN / (factR * factNMR);

        System.out.println(BinCo);

    }

}
