What other containers are there in the Collections API besides arrays?

In the Java Collections API, besides arrays (represented by the Array class and not part of collections), there are various containers for storing and managing groups of objects:

• List — an ordered list of elements allowing duplicates. Examples: ArrayList, LinkedList.
• Set — a collection of unique elements without a specific order (or with a specific order, like in LinkedHashSet or TreeSet).
• Queue — a queue, usually for processing elements in FIFO order. Examples: LinkedList, PriorityQueue.
• Deque — a double-ended queue, allowing adding and removing elements from both ends. Example: ArrayDeque.
• Map — a collection of key-value pairs where keys are unique. Examples: HashMap, TreeMap, LinkedHashMap.

Each of these containers serves different purposes and has its own features regarding performance and functionality.
