    Subclasses of AbstractCollection in java.util
    Modifier and Type | Class and 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.

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

    Subclasses of AbstractCollection in java.util.concurrent
    Modifier and Type | Class and 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.

    `class` | `RoleList` A RoleList represents a list of roles (Role objects).
    `class` | `RoleUnresolvedList` A RoleUnresolvedList represents a list of RoleUnresolved objects, representing roles not retrieved from a relation due to a problem encountered when trying to access (read or write) the roles.

    `class` | `JobStateReasons` Class JobStateReasons is a printing attribute class, a set of enumeration values, that provides additional information about the job's current state, i.e., information that augments the value of the job's `JobState` attribute.
