16.13 Abstract Implementations

The collections framework provides various abstract implementations of Collection interfaces from which you can quickly “flesh out” complete customized implementations. These abstract implementations include a thin Collection implementation called an AbstractCollection, a List implementation that allows array-like access to its elements called an AbstractList, a Map implementation called an AbstractMap, a List implementation that allows sequential access (from beginning to end) to its elements called an AbstractSequentialList, a Set implementation called an AbstractSet and a Queue implementation called AbstractQueue.
