Java program to multiply corresponding elements of two lists

Program to multiply corresponding elements of two array lists in java

import java.util.Arrays;

public class ExArrayMultiplyCorresElem {
  public static void main(String[] args) {
    // take a default string array you wants.
    String result = "";
    int[] left_array = {
      2,
      -5,
      4,
      -2
    };
    int[] right_array = {
      6,
      4,
      -5,
      -2
    };

    // print both the string array first.
    System.out.print("\nArray1: " + Arrays.toString(left_array));
    System.out.println("\nArray2: " + Arrays.toString(right_array));
    for (int i = 0; i < left_array.length; i++) {
      int num1 = left_array[i];
      int num2 = right_array[i];

      // this will calculate the product of the string array.
      result += Integer.toString(num1 * num2) + " ";
    }
    // print the result.
    System.out.println("\nResult: " + result);
  }
}

Output

Array1: [2, -5, 4, -2]
Array2: [6, 4, -5, -2]

Result: 12 -20 -20 4
