    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 predictable iteration 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.

    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 can only be taken 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.
