Q1. Java hash map and how it works
Ans. 
Java hash map is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values based on keys.
• HashMap in Java implements the Map interface and allows null keys and values.

• Example: HashMap map = new HashMap<>(); map.put("key", 1); int value = map.get("key");
