Output:

Explanation:
• This program calculates the sum of elements in an array of integers.
• It initializes an array numbers with values {1, 2, 3, 4, 5}.
• It iterates through each element of the array using a for loop and adds each element to the variable sum.
• Finally, it prints the sum of the array elements.

TASK 1_Method2: Java program that allows the user to input array elements through the keyboard and
displays the sum of those elements

Here’s a Java program that allows the user to input array elements through the keyboard and displays the sum
of those elements:

//Sum of array elements
import java.util.Scanner;
public class ArraySum {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

// Prompt the user to enter the size of the array
System.out.print(“Enter the size of the array: “);
int size = scanner.nextInt();

// Create an array of the specified size
int[] numbers = new int[size];

// Prompt the user to enter array elements

System.out.println(“Enter the elements of the array:”);
for (int i = 0; i < size; i++) {
System.out.print(“Element “ + (i + 1) + “: “);
numbers[i] = scanner.nextInt();
}
