Java Program to Find Product of Two Numbers using Recursion

This is a Java Program to Find Product of 2 Numbers using Recursion.

Enter two integer numbers as an input. After that we pass the two given numbers along with zero to the other function where get numbers one by one to multiply with the help of recursion. Hence we get the product of the two given numbers as an output.

Here is the source code of the Java Program to Find Product of 2 Numbers using Recursion. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.

  1. import java.util.Scanner;
  2. public class Multiply_Recursion 
  3. {
  4.     public static void main(String[] args) 
  5.     {
  6.         int[] a = new int[2];
  7.         Scanner s = new Scanner(System.in);
  8.         System.out.print("Enter the first number:");
  9.         a[0] = s.nextInt();
  10.         System.out.print("Enter the second number:");
  11.         a[1] = s.nextInt();
  12.         Multiply_Recursion obj = new Multiply_Recursion();
  13.         int mul = obj.multiply(a,0);
  14.         System.out.println("Answer:"+mul);
  15.     } 
  16.    int multiply(int x[], int i)
  17.     {
  18.         if(i < 2)
  19.         {
  20.             return x[i] * multiply(x, ++i);
  21.         }
  22.         else
  23.         {
  24.             return 1;
  25.         }
  26.     }
  27. }

Output:

$ javac Multiply_Recursion.java
$ java Multiply_Recursion
 
Enter the first number:6
Enter the second number:4
Answer:24
