An abstract method has no body, which means it can’t be defined inside an abstract class. However, we can define an abstract method inside the derived class of the same abstract class.
In Kotlin, an interface can’t store a state and is allowed to have properties that must be of an abstract nature.
By default, all methods and variables are non-abstract. To override these methods and variables inside a derived class, we need to define them with the open keyword.
