  • Q1. How can you create immutable class in Java?
  • Ans. 

    Immutable class in Java cannot be modified after creation, ensuring data integrity.

    • Make the class final so it cannot be extended

    • Make all fields private and final so they cannot be modified

    • Do not provide setter methods, only getter methods to access the fields

    • If the class contains mutable objects, make sure to return a deep copy of them in getter methods

  • Answered by AI
  • Q2. 1 : Declare the class as final. 2 : Make all fields private and final. 3 : Provide no setter methods.
  • Ans. 

    The question is asking to create a class with certain restrictions like being final, having private and final fields, and no setter methods.

    • Declare the class as final to prevent it from being subclassed.

    • Make all fields private and final to ensure encapsulation and immutability.

    • Provide no setter methods to enforce read-only access to the fields.
