Q1. How hashmap works in java?
Ans. 
HashMap in Java is a data structure that stores key-value pairs and allows fast retrieval of values based on keys.
• HashMap uses hashing to store key-value pairs in an array of linked lists.

• It allows null keys and values.

• HashMap provides constant-time performance for basic operations like get and put.

• Example: HashMap<String, Integer> map = new HashMap<>(); map.put("key1", 1); int value = map.get("key1");
