Arrays

Java provides a data structure, the array, which stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

This tutorial teaches you how to define array variables, build arrays, and process arrays using indexed variables.
