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.
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.

Commonly used in scenarios where a single instance needs to coordinate actions across the system.
Example: Database connection manager, logger, configuration manager.
