Java program for Multiplication of Array elements.


To find the product of elements of an array.

  • create an empty variable. (product)
  • Initialize it with 1.
  • In a loop traverse through each element (or get each element from user) multiply each element to product.
  • Print the product.

Example

 Live Demo

import java.util.Arrays;
import java.util.Scanner;
public class ProductOfArrayOfElements {
   public static void main(String args[]){
      System.out.println("Enter the required size of the array :: ");
      Scanner s = new Scanner(System.in);
      int size = s.nextInt();
      int myArray[] = new int [size];
      int product = 1;
      System.out.println("Enter the elements of the array one by one ");
      for(int i=0; i<size; i++){
         myArray[i] = s.nextInt();
         product = product * myArray[i];
      }
      System.out.println("Elements of the array are: "+Arrays.toString(myArray));
      System.out.println("Sum of the elements of the array ::"+product);
   }
}

Output

Enter the required size of the array:
5
Enter the elements of the array one by one
11
65
22
18
47
Elements of the array are: [11, 65, 22, 18, 47]
Sum of the elements of the array:13307580
