6 min readIn Kotlin, you can implement inheritance using the open and class keywords. The open keyword is used to mark a class as open so that it can be inherited, and the class keyword is used to define a new class.To inherit from a class, you use the : symbol followed by the name of the superclass. The class that inherits from another class is known as the subclass. Note that by default, all classes in Kotlin are final and cannot be inherited.
