Create a recursive function to multiply

Create a recursive function to multiply

Monday, November 13, 2023 ⁃ Difficulty: Intermediate

Objective

Create a Java program that implements a recursive function called multiply() which takes two integers inputted by the user and returns the result of their multiplication.

Instructions

From the main function (main) of the program, prompt the user to input two integers.
Implement a recursive function named multiply that takes the two inputted numbers as parameters and returns the result of their multiplication.
Print the result of the multiplication to the screen.

Input

4
4

Output

Solution

RecursiveMultiplyFunction.java

import java.util.Scanner;

public class RecursiveMultiplyFunction {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int number1 = scanner.nextInt();
        int number2 = scanner.nextInt();

        System.out.println(multiply(number1, number2));
    }

    public static int multiply(int number1, int number2) {
        if (number2 == 0) {
            return 0;
        } else {
            return number1 + Multiply(number1, number2 - 1);
        }
    }
}
