Answer from AI

The Java Collections Framework includes several standard data structures:

  • List — an ordered list of elements that allows duplicates. Implementations: ArrayList, LinkedList.
  • Set — a collection of unique elements without duplicates. Implementations: HashSet, LinkedHashSet, TreeSet.
  • Queue — a collection for storing elements in a specific order of retrieval. Implementations: LinkedList, PriorityQueue.
  • Deque — a double-ended queue supporting insertion and removal from both ends. Implementations: ArrayDeque, LinkedList.
  • Map — a key-value mapping with unique keys. Implementations: HashMap, LinkedHashMap, TreeMap, Hashtable.

Each data structure has its own features and is used depending on performance and functionality requirements.
