  • What is difference between interface and abstract class?

    The Abstract class and Interface both are used to have abstraction. An abstract class contains an abstract keyword on the declaration whereas an Interface is a sketch that is used to implement a class. Explore more differences between abstract class and interface in java.

  • When should you use abstract class vs interface?

    If you are creating functionality that will be useful across a wide range of objects, then you must use an interface. Abstract classes, at the end of the day, should be used for objects that are closely related. But the interfaces are best suited for providing common functionality to unrelated cases.

  • What is the difference between interface and abstract class in Kotlin?
