What collection framework interfaces do you know? What common parent do List, Set, Queue, Map have?

In the Java Collection Framework, the main interfaces are:

• Collection — the base interface for most collections (except Map).
• List — an ordered collection that allows duplicates (e.g., ArrayList, LinkedList).
• Set — a collection of unique elements (e.g., HashSet, TreeSet).
• Queue — a collection for storing elements in processing order (e.g., LinkedList, PriorityQueue).
• Deque — a double-ended queue.
• Map — a collection of key-value pairs, does not inherit from Collection.

Common parent interfaces:

• List, Set, and Queue inherit from the Collection interface.
• Map does not inherit from Collection but is part of the Collection Framework.

Example:

List<String> list = new ArrayList<>();
Set<Integer> set = new HashSet<>();
Queue<Double> queue = new LinkedList<>();
Map<String, Integer> map = new HashMap<>();
