In the Strategy Pattern, deciding whether a method should be abstract or encapsulated in an interface depends on the desired level of flexibility and the specific use case. If multiple concrete strategies will share a common implementation or partially reusable behavior, using an abstract class allows you to define shared logic while still allowing customization in subclasses. However, if the goal is to maximize flexibility and enforce a strict contract without concern for shared behavior, encapsulating the method in an interface is preferable. Interfaces promote loose coupling by defining the behavior that all strategies must implement, enabling the swapping of strategies at runtime without dependency on implementation details. For highly reusable and interchangeable strategies, prioritize interfaces; for shared functionality within a hierarchy, consider an abstract class.

I believe while using the strategy pattern while implementing both abstract classes and interfaces should be fine, depending on the amount of flexibility the method requires as in strategic patterns can change algorithms during runtime.
