Ans. 
Hashmap is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.

• It allows for constant time complexity O(1) for insertion, deletion, and retrieval operations.

• Example: HashMap<String, Integer> map = new HashMap<>(); map.put("key", 123); int value = map.get("key");
