Java Exercises: Multiply corresponding elements of two arrays of integers
Java Basic: Exercise-83 with Solution
Write a Java program to multiply corresponding elements of two arrays of integers.
Sample Solution:
Java Code:
import java.util.*;
public class Exercise83 {
public static void main(String[] args){
String result = "";
int[] left_array = {1, 3, -5, 4};
int[] right_array = {1, 4, -5, -2};
System.out.println("\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];
result += Integer.toString(num1 * num2) + " ";
}
System.out.println("\nResult: "+result);
}
}
Sample Output:
Array1: [1, 3, -5, 4] Array2: [1, 4, -5, -2] Result: 1 12 25 -8
