Round 1 - Technical 

(1 Question)

  • 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.

    • It uses hashing to store and retrieve key-value pairs, providing O(1) time complexity for get() and put() operations.

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