Answer from AI
Besides Map, Java has several main collection data structures:
- List — an ordered list of elements, allows duplicates. For example, ArrayList, LinkedList.
- Set — a collection of unique elements without a specific order. For example, HashSet, TreeSet.
- Queue — a queue where elements are processed in FIFO order. For example, LinkedList, PriorityQueue.
- Deque — a double-ended queue that allows adding and removing elements from both ends.
Each of these structures has its own features and is used depending on the task.
