Why does polymorphism on caller coupling matter in practice?
Track: Java
Topic: OOP

Java: Polymorphism
Answer
Polymorphism reduces caller coupling by allowing the use of interface types instead of concrete classes.
By programming to an interface rather than a concrete class, polymorphism reduces dependencies between modules. This means that changes to a class do not necessarily impact its callers. For example, if a payment processing system uses a `PaymentProcessor` interface, the system can switch from `PaypalProcessor` to `StripeProcessor` without altering the surrounding code.
