What is arrays in Java?

Arrays in Java are a data structure that allows you to store multiple values of the same type in a single variable. An array is a fixed-size data structure, which means that once it is created, its size cannot be changed. Each element in an array can be accessed using its index, which starts at 0. Arrays are particularly useful when you want to store related data items or when you need to perform operations on multiple items in a loop.

Example of an Array in Java:

int[] numbers = {1, 2, 3, 4, 5}; for (int i = 0; i < numbers.length; i++) { System.out.println(numbers[i]); }
