  • Q1. Does Java support pass by reference?
  • Ans. 

    Yes

    • Java uses pass by value for all variables, including object references.

    • When an object reference is passed as an argument, a copy of the reference is passed, not the actual object.

    • Modifying the reference inside the method will not affect the original reference outside the method.

    • However, modifications to the object's state inside the method will be visible outside the method.

  • Answered by AI
  • Q2. Explain Singleton Pattern
  • Ans. 

    Singleton pattern restricts the instantiation of a class to a single object.

    • Singleton pattern ensures that only one instance of a class exists throughout the application.

    • It provides a global point of access to the instance.

    • Commonly used in scenarios where a single instance needs to coordinate actions across the system.

    • Example: Database connection manager, logger, configuration manager.
