array Modifier Program

In this problem, you will create a program that passes an array {5, 10, 15} to a doubleValues() method, doubles each element, and displays the array before and after modification to standard output.

Learning Objective: Understand that modifying reference type arguments (arrays) inside a method affects the caller

Overview

Create a program that passes an array to a method and modifies the array elements inside the method. Learn how changes to reference type arguments are reflected in the caller.

Specifications

1. Define a doubleValues() method:

   • Receives an int array as an argument
   • Doubles each element of the array

2. In Main class:

   • Create an array with {5, 10, 15}
   • Output the array before modification as Before: 5, 10, 15
   • Call doubleValues()
   • Output the array after modification as After: 10, 20, 30

Output Format

Before: 5, 10, 15
After: 10, 20, 30

Hints

• Modifying reference type arguments changes the caller's array too
• Modify array element: numbers[i] = numbers[i] * 2;
