- We spoke about base classes and derived classes in this part. What is the difference between the general and specialised classes?arrow_forwardA subclass must fully implement all of the abstract methods of its parent class in order to be considered a subclass of an abstract class. What are your thoughts on whether or not it should be done?arrow_forward2 Javaarrow_forward
- With appropriate examples, explain the features of static class members.arrow_forwardExamine the role of access keywords in defining class members.arrow_forwardB and C are its subclasses, and A is the parent class. Now, B and C have certain similar features and methods, but B and C implement a number of their methods very differently. Use logic to specify if A is a concrete class, an abstract class, or an interface.arrow_forward
- i codecheck.it/files/20072604422gi2zqg7qx7iflhyuOne6naif Problem Statement Inheritance Write the Bicyle class which extends Vehicle. The UML diagram is shown below. Follow it exactly. Vehicle Class Fields owner: string wheels : int Methods • getwheels): int tostring): string • vehide(string owner, int wheels) Bkycle Class vehicle Fields gears : int model 1 string Methods • Bicyde(string o, int w, string mod, int gear) • getGearRatio): int tetring): string • The Bicycle constructor call the superclass constructor to initialize owner and wheels • getGearRatio) returns the product of gears and wheels. (Stupid, I know.) • Override the toString) method and return the information in this form, all on one line: Bicycle(model="Trek T700", gears=21) extends Vehicle(owner="V. Nibali", wheels=2)arrow_forwardQuèstion 5 To convert from superclass type to subclass, we use: a. overloading Ob. explicit casting overriding C. d. implicit castingarrow_forwardWhen inheriting from an abstract class, a subclass is obligated to implement each and every one of the abstract methods that the parent class provides. Is there a mistake in my understanding of this?arrow_forward
- A is the parent class, while B and C are the subclasses. While B and C have certain similarities in terms of features and methods, their implementations of some of their methods are rather different. Justify your choice of A as a concrete class, an abstract class, or an interface using logic.arrow_forwardjust mention the Anwsers. Explanation is not needed.
