Weite java code to implement given statements An abstract class must be declared with an abstract keyword. • It can have abstract and non-abstract methods. • It cannot be instantiated. • It can have constructors and static methods also. • It can have final methods which will force the subclass not to change the body of the method.

Class A is the parent class, while classes B and C are the subclasses of A. Both B and C contain several features and techniques that are equivalent to one another; nevertheless, the implementations of some of their methods are quite different between the two. Explain what kind of class A will be using logic, whether it be a concrete class, an abstract class, or an interface.
To be a subclass of an abstract class, a subclass must implement all of its parent's abstract methods. Is this right or incorrect?

Read a UML diagram to determine the new methods and or instance variables. Define instance variables, accessors, and mutators. Define a constructor to initialize those variables. Define constructors for your subclasses and call the superclass constructor. Override superclass methods, by combining and extending their behavior. Override the toString method in a subclass. There is no printing and you will not need Scanners, or do any input. Inheritance Write the Bicyle class which extends Vehicle. The UML diagram is shown below. Follow it exactly. 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)
A 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?
When 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?
Class A is the parent class, while classes B and C are the subclasses of A. Both B and C contain several features and techniques that are equivalent to one another; nevertheless, the implementations of some of their methods are quite different between the two. Explain what kind of class A will be using logic; is it going to be a concrete class, an abstract class, or an interface?
A subclass of an abstract class must be able to do all of the things the parent class can do. True or not?
Subject: Java Programming Question#1: Define an abstract class LivingBeing. Define abstract methods breath, sleep, eats. Define Subclasses Animal and Plants. Override the base methods and call them polymorphically.
A is the superclass, whereas B and C are the subclasses. While B and C have certain similarities in terms of features and methods, their implementations of some methods are rather different. Justify your choice of A: a concrete class, an abstract class, or an interface using logic.
Implement all the classes using Java programming language from the given UML Class diagram. Note: This problem requires you to submit just two classes: Circle.java, Cylinder.java. Do NOT include "public static void main()" method inside all of these classes. In this exercise, a subclass called Cylinder is derived from the superclass Circle as shown in the class diagram (where an arrow pointing up from the subclass to its superclass). Study how the subclass Cylinder invokes the superclass' constructors (via super() and super(radius)) and inherits the variables and methods from the superclass Circle. You can reuse the Circle class that you have created in the previous exercise. Make sure that you keep "Circle.class" in the same directory. Method Overriding and "Super": The subclass Cylinder inherits getArea() method from its superclass Circle. Try overriding the getArea() method in the subclass Cylinder to compute the surface area (=π×radius×radius×height) of the cylinder instead of the…
Java programming Help us set up the student system! 2.a) Write an abstract class Student describing (students) (2 properties and 1 method)! (Be carefull when defining the method!) 2.b) Extend the Student class into three new classes that can be directly instantiated: UndergraduateStudend, PostgraduateStudent, FailedStudent (each should have one additional property)! 2.c) Use all appropriate classes in a special School class!
