Interfaces were introduced a few versions ago but now you can extend one or more existing interfaces when you declare an interface. When implementing an interface you’re signing a contract, through which you must implement all methods from all extended interfaces.
Benefits of using Interfaces
Enhanced Readability and Maintenance: They serve as documentation by clearly defining what each component does, making it easier for other developers to understand and work with the system.
Enforced Consistency: When multiple objects implement the same interface, they all adhere to the same method signatures and structure. This uniformity across implementations makes it easier to maintain code and ensures consistency.
