The standard collection classes are summarized in the following table:
| Class | Description |
| AbstractCollection | Implements most of the Collection interface. |
| AbstractList | Extends AbstractCollection and implements most of the List interface. |
| AbstractQueue | Extends AbstractCollection and implements parts of the Queue interface. |
| AbstractSequentialList | Extends AbstractList for use by a collection that uses sequential rather than random |
| access of its elements. | |
| LinkedList | Implements a linked list by extending AbstractSequentialList. |
| ArrayList | Implements a dynamic array by extending AbstractList. |
| ArrayDeque | Implements a dynamic double-ended queue by extending AbstractCollection and |
| implementing the Deque interface. (Added by Java SE 6.) | |
| AbstractSet | Extends AbstractCollection and implements most of the Set interface. |
| EnumSet | Extends AbstractSet for use with enum elements. |
| HashSet | Extends AbstractSet for use with a hash table. |
| LinkedHashSet | Extends HashSet to allow insertion-order iterations. |
| PriorityQueue | Extends AbstractQueue to support a priority-based queue. |
| TreeSet | Implements a set stored in a tree. Extends AbstractSet. |
