WebAbstraction can be achieved with either abstract classes or interfaces (which you will learn more about in the next chapter). The abstract keyword is used for classes and methods: Abstract class: is a restricted class that cannot be used to create objects (to access it, it must be inherited from another class). WebJun 11, 2024 · In order to call the methods using interface reference (here r is interface reference), you have to assign to class object to it. Like if you are assigning Person1’s object obj1 to r i.e. r = obj1; then you call the Speed () and Distance () methods that are implemented by the Person1 class.
