Create a Java program to find the factorial using recursive and iterative method

 

public class CDM_varargs {
    static int factorial(int n){
        if(n==0 || n==1){
            return 1;
        }
        else{
            return n*factorial(n-1);

        }
    }
    static int factorial_iterative(int n){
        if(n==0 || n==1){
            return 1;
        }
        else{
            int product = 1;
            for(int i =1; i<=n; i++){
                product = product*i;

            }
            return product;

        }
    }

    public static void main(String[] args) {
        int x= 5;
        System.out.println(" The value of factorial x is :" + factorial(x));
        System.out.println(" The value of factorial x is :" + factorial_iterative(x) );
    }
}
//output
 The value of factorial x is :120
 The value of factorial x is :120
