    • Allows loose coupling between objects

    • Example: A weather station broadcasts weather updates to multiple displays

    • Example: A stock market ticker notifies multiple investors of stock price changes

  • Ans. 

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

    • 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.

    • It allows for easier swapping of dependencies without changing the code.

    • There are three types of dependency injection: constructor injection, setter injection, and interface injection.

    • Example: Instead of creating a database co...
