- A subclass of an abstract class is required to implement all of the abstract methods of the parent class. Is it correct or incorrect?Explain the difference between the following implementations of class A.a. extending class A from class Bb. extending class A from parent abstract class Cc. class A implementing interface DWrite an abstract class, it can be anything well defined from the very basics.
- A subclass of an abstract class must implement all of the parent class's abstract methods. Is it true or false?For your application, explain the benefits of interfaces over abstract classes.Abstract classes and interfaces may be used interchangeably to specify the behavior of objects.How do you know whether you need an interface or an abstract class?
- Object models, as well as the concepts of encapsulation and polymorphism, are inexorably intertwined.What is fundamental difference/s between an abstract classes and interfaceIn Java, which of the following is false? An abstract class may implement an interface. A class that contains an abstract method must be declared abstract itself or a compiler message will result. A class may implement multiple interfaces. A class that extends another class may implement only one interface.
- Please define two interface Auto and Sprinkler, and three classes Car, Truck and FireTruck. Car and Truck are going to implement Auto. Fi reTruck is going to extend Truck, and implement Sprinkler. interface Auto { public abstract void move(); public abstract void stop(); public abstract void dudu(); interface Sprinkler { } public abstract void watering(); public class Main { public static void main(String args[]) { Car car= new Car(); } car.move(); car.dudu(); car.stop(); FireTruck firetruck = new FireTruck(); firetruck.move(); firetruck.dudu(); firetruck.stop(); firetruck.watering();Write the Talker interface, Animal abstract class, plus the Dog, Cat, Fish, and Radio classes for this Java Program. Talker.java - the interface Talker, which has just one void method called speak() Animal.java - the abstract class Animal, which stores an animal's name. (No abstract methods). It should contain 2 methods: a constructor with 1 argument (the name) a method getName() which returns the name. Dog.java - the class Dog, which extends Animal and implements Talker. It should contain 3 methods: a constructor with no arguments, giving the dog a default name of "Fido" a constructor with 1 argument (the name) a speak() method that prints "Woof" on the screen. Use @Override Cat.java - the class Cat, which extends Animal and implements Talker. It should contain just 2 methods: a constructor with 1 argument (the name) (no default name like dogs have) a speak() method that prints "Meow" on the screen. Use @Override Fish.java - the class Fish, which is an Animal that…A subclass of an abstract class must implement all abstract methods of the parent class. True or false
