Java: Upcasting and Dynamic Dispatch
Answer
Abstraction simplifies complex systems by hiding details.
Abstraction allows you to define a class with essential attributes and methods, omitting finer details. This makes the system easier to manage and extend. For example, an abstract `Service` class might define `execute()` without detailing how each service type, like `Shipping` or `Billing`, executes.
