Can you name alternative data structures other than ArrayList and LinkedList?

Besides ArrayList and LinkedList, there are other data structures in Java that can be used depending on the task:

• HashSet — a set based on a hash table, providing fast search and element uniqueness.
• TreeSet — a set based on a red-black tree, storing elements in sorted order.
• HashMap — a map (key-value) with quick access by key.
• TreeMap — a map with sorted keys.
• Stack — a "stack" data structure (LIFO), implemented as a class.
• Queue and Deque — queues and double-ended queues for organizing the order of element processing.

The choice of structure depends on requirements for access speed, insertion, deletion, and element order.
