Q5. Internal working principle of hashmap.

Ans.

HashMap is a data structure that stores key-value pairs and uses hashing to quickly retrieve values based on keys.

  • If multiple keys hash to the same index, a collision occurs and the key-value pairs are stored in a linked list at that index.

  • To retrieve a value, the key is hashed again to find the...read more

  • Threads can be created in programming languages like Java, C++, and Python using built-in libraries or frameworks.

  • For example, in Java, you can create a thread by extending the Thread class or implementing the Runnable inter...read more
