Uses of Collection in java.util

Subinterfaces of Collection in java.util
`interface` | `List` An ordered collection (also known as a sequence).
`interface` | `Set` A collection that contains no duplicate elements.
`interface` | `SortedSet` A set that further guarantees that its iterator will traverse the set in ascending element order, sorted according to the natural ordering of its elements (see Comparable), or by a Comparator provided at sorted set creation time.

Classes in java.util that implement Collection
`class` | `AbstractCollection` This class provides a skeletal implementation of the `Collection` interface, to minimize the effort required to implement this interface.
`class` | `AbstractList` This class provides a skeletal implementation of the `List` interface to minimize the effort required to implement this interface backed by a "random access" data store (such as an array).
`class` | `AbstractSequentialList` This class provides a skeletal implementation of the `List` interface to minimize the effort required to implement this interface backed by a "sequential access" data store (such as a linked list).
`class` | `AbstractSet` This class provides a skeletal implementation of the `Set` interface to minimize the effort required to implement this interface.
`class` | `ArrayList` Resizable-array implementation of the `List` interface.
`class` | `HashSet` This class implements the `Set` interface, backed by a hash table (actually a `HashMap` instance).
`class` | `LinkedList` Linked list implementation of the `List` interface.
`class` | `Stack` The `Stack` class represents a last-in-first-out (LIFO) stack of objects.
`class` | `TreeSet` This class implements the `Set` interface, backed by a `TreeMap` instance.
`class` | `Vector` The `Vector` class implements a growable array of objects.
