Answer
Abstract methods enforce shared behavior by requiring implementation in subclasses.
Abstract methods in an abstract class must be implemented by any concrete subclass, ensuring that all subclasses share a certain behavior. For example, in an e-commerce system, an abstract class 'User' might have an abstract method 'getUserRole'. Every subclass, like 'AdminUser' or 'CustomerUser', must implement this method, ensuring all user types have a defined role.
