![]() We cannot use the backing field from Properties in interfaces since an interface doesn’t store any state and hence no previous values.Interfaces are useless unless they’re implemented by a class. We need to implement all the abstract properties of the interface or else set the class as an abstract class. Operations that are the same in Java and Kotlin In Kotlin, there are many operations on collections that look exactly the same as their counterparts in Java. A class can implement multiple interfaces too using the above concept. properties that provide accessor implementations but can’t store the state.Built to be fully interoperable with Java to facilitate industry-wide adoption and easy, gradual migration, Kotlin. Java and Kotlin are two extremely popular programming languages in the software development realm. declarations of abstract methods and method implementations Kotlin is Google’s chosen successor to Java for Android app development.With the interface, you can define a set of properties and methods, that is used by classes for specific behaviors. Instead, these define a form of behavior (like contracts) that the implementing types have to follow. ![]() ![]() Interfaces are custom types provided by Kotlin that cannot be instantiated directly. ![]() type aliases? 10- why can’t use Generic inside Interface Declaration? 11- default function implementation of interface? what are Interface and its property? 1- what is Interface and its property? 2- why an interface can’t store the state? 3- How to Implement interface property in Concrete type? 4- what happens if the class implements multiple interfaces and both the interfaces have the same functions? 5- interface difference in Java and Kotlin 6- Functional interfaces(SAM Single Abstract Method) 7- Use a lambda in place of a functional interface? 8- Why use Object Expressions to instiate anonymous interface? 9- Functional interfaces vs.
