Array Sum Calculator

In this problem, you will create a program that reads array elements from standard input, passes them to a sumArray() method, and prints the sum of all elements.

Learning Objective: Understand how to pass reference types (arrays) as method arguments

Overview

Read the array size and elements using Scanner, pass the array to a method, compute the total sum, and print it. Learn the basics of reference type arguments.

Specifications

1. Define a sumArray() method:

   • Receives an int array as an argument
   • Computes and returns the sum of all array elements (return type: int)

2. In Main class:

   • Line 1: Read N (the number of elements)
   • Line 2: Read N space-separated integers into an array
   • Call sumArray() passing the array and print the result

Input/Output Example

Input:
3
10 20 30

Output:
60

Input:
5
1 2 3 4 5

Output:
15

Hints

• Create a Scanner with Scanner scanner = new Scanner(System.in);
• Use scanner.nextInt() to read one integer at a time
• Specify array as method parameter like int[] numbers
• Use a for loop to accumulate each element
• Initialize a sum variable to 0 before the loop
