  Subclasses of AbstractCollection in java.util
  Modifier and Type
  Class
  Description
  `class`
  `AbstractList<E>`
  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`
  `AbstractQueue<E>`
  This class provides skeletal implementations of some `Queue` operations.
  `class`
  `AbstractSequentialList<E>`
  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<E>`
  This class provides a skeletal implementation of the `Set` interface to minimize the effort required to implement this interface.
  `class`
  `ArrayDeque<E>`
  Resizable-array implementation of the `Deque` interface.
  `class`
  `ArrayList<E>`
  Resizable-array implementation of the `List` interface.
  `class`
  `EnumSet<E extends Enum<E>>`
  A specialized `Set` implementation for use with enum types.
  `class`
  `HashSet<E>`
  This class implements the `Set` interface, backed by a hash table (actually a `HashMap` instance).
  `class`
  `LinkedHashSet<E>`
  Hash table and linked list implementation of the `Set` interface, with well-defined encounter order.
  `class`
  `LinkedList<E>`
  Doubly-linked list implementation of the `List` and `Deque` interfaces.
  `class`
  `PriorityQueue<E>`
  An unbounded priority queue based on a priority heap.
  `class`
  `Stack<E>`
  The `Stack` class represents a last-in-first-out (LIFO) stack of objects.
  `class`
  `TreeSet<E>`
  A `NavigableSet` implementation based on a `TreeMap`.
  `class`
  `Vector<E>`
  The `Vector` class implements a growable array of objects.

- ## Uses of AbstractCollection in java.util.concurrent

  Subclasses of AbstractCollection in java.util.concurrent
  Modifier and Type
  Class
  Description
  `class`
  `ArrayBlockingQueue<E>`
  A bounded blocking queue backed by an array.
  `class`
  `ConcurrentLinkedDeque<E>`
  An unbounded concurrent deque based on linked nodes.
  `class`
  `ConcurrentLinkedQueue<E>`
  An unbounded thread-safe queue based on linked nodes.
  `class`
  `ConcurrentSkipListSet<E>`
  A scalable concurrent `NavigableSet` implementation based on a `ConcurrentSkipListMap`.
  `class`
  `CopyOnWriteArraySet<E>`
  A `Set` that uses an internal `CopyOnWriteArrayList` for all of its operations.
  `class`
  `DelayQueue<E extends Delayed>`
  An unbounded blocking queue of `Delayed` elements, in which an element generally becomes eligible for removal when its delay has expired.
  `class`
  `LinkedBlockingDeque<E>`
  An optionally-bounded blocking deque based on linked nodes.
  `class`
  `LinkedBlockingQueue<E>`
  An optionally-bounded blocking queue based on linked nodes.
  `class`
  `LinkedTransferQueue<E>`
  An unbounded `TransferQueue` based on linked nodes.
  `class`
  `PriorityBlockingQueue<E>`
  An unbounded blocking queue that uses the same ordering rules as class `PriorityQueue` and supplies blocking retrieval operations.
  `class`
  `SynchronousQueue<E>`
  A blocking queue in which each insert operation must wait for a corresponding remove operation by another thread, and vice versa.
