    • Make all fields private and final

    • Do not provide setter methods for the fields

    • Ensure that any mutable objects within the class are also immutable

    • If a mutable object must be returned, make a deep copy before returning it

  • Answered by AI
  • Q6. Design patterns :Singleton and factory
  • Q7. What are the different types of dependency injection?
  • Ans. 

    Types of dependency injection include constructor injection, setter injection, and interface injection.
