Java Arrays

What is an Array?

An array is a fixed-size collection of elements of the same type, stored in contiguous memory and accessed by index (starting at 0).

Declaring and Using Arrays

int[] numbers = {10, 20, 30};
System.out.println(numbers[0]); // 10
System.out.println(numbers.length); // 3

Why Testers Use Arrays

Arrays are handy for holding a fixed set of test data (like a list of expected status codes) that a test loops through and verifies.
