When you have more than a couple of data objects, you can manage them in app memory using Java collections. The most commonly used of these are the List and Map interfaces, using concrete implementations ArrayList and HashMap. The List is an ordered collection, like a resizable array, and the Map is an unordered collection of key-value pairs. If you’re unfamiliar with these Java interfaces and classes, you can learn about them in the course Java Essential Training, in the chapter “Using Data Collections”.
