  • Q1. What is hashcode method does?
  • Ans. 

    The hashcode method in Java returns the hash code value for an object.

    • Returns an integer value representing the object's memory address

    • Used for efficient storage and retrieval in hash-based collections like HashMap

    • Should be overridden in custom classes to ensure proper functionality

  • Answered by AI
  • Q2. What is internal workingd of Hashmap
  • Ans. 

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

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

    • When a key-value pair is added, the key is hashed to determine its index in the array.

    • If multiple keys hash to the same index, a linked list is used to handle collisions.

    • To retrieve a value, the key is hashed again to find the correct index and then the l...

  • Q3. What is method overriding and overloading
  • Ans. 

    Method overriding is when a subclass provides a specific implementation of a method that is already provided by its parent class. Method overloading is when multiple methods have the same name but different parameters.

    List allows duplicate elements and maintains insertion order, while Set does not allow duplicates and does not maintain order.

    • List can contain duplicate elements, Set cannot

    • List maintains insertion order, Set does not guarantee order

    • List is implemented by classes like ArrayList, LinkedList, Set is implemented by classes like HashSet, TreeSet

    • Example: List list = new ArrayList<>(); Set set = new HashSet<>();
