Java Interface Kullanımı. In java we can achieve abstraction using interfaces and abstract classes. çünkü interface içinde sadece soyut fonksiyonlar tanımlayabilirsiniz.
This flexibility also called abstraction allows us to think in more general terms about the domain were trying to model. Interface method does not have a body public void run. An interface is a completely abstract class that is used to group related methods with empty bodies.
Interfaces form a contract between the class and the outside world and this contract is enforced at build time by the compiler.
Compare interfaces and abstract classes both are used to achieve abstraction. Kotlin supports sam conversions for both java and kotlin interfaces. An abstract class can have concrete implementations an interface cannot. Desteklenmeyen bir iş yapmaya.
