  • Q1. Internal working of hashmap
  • Ans. 

    HashMap is a data structure that stores key-value pairs and uses hashing to efficiently retrieve values.

    • HashMap internally uses an array of linked lists to store key-value pairs.

    • When a key-value pair is added, the key is hashed to find the index in the array where it will be stored.

    Singleton class is a class that can only have one instance and provides a global point of access to it.

    • It provides a way to access its unique instance globally.

    • Commonly used in scenarios where only one instance of a class is needed, such as database connections or thread pools.
