Java Collections: List, Set, Map

Java Collections: List, Set, Map (http://web.mit.edu/6.031/www/sp17/classes/02-basic-java/#java_collections)

A List contains an ordered collection of zero or more objects, where the same object might appear multiple times.

A Set is an unordered collection of zero or more unique objects.

A Map is similar to a dictionary (key, value).
