An array is an example of a data structure, which allows multiple elements to be stored in a single variable. Java includes many other data structures as well, in the java.util package. Each is used to handle data in different ways. ... Tip: Data structures are like supercharged arrays - more flexible and feature-rich! We'll explore all of these - and many more - in detail later, but for now, here's a quick introduction to each one. An ArrayList is a resizable array that can grow as needed.
