Explain the difference between the following implementations of class A. a. extending class A from class B b. extending class A from parent abstract class C c. class A implementing interface D

Task: Implement a class ChessPiece with properties: color, isAlive, moveCount, and position (x, y coordinates). Define an abstract move method. Create a Tower subclass that overrides move for specific behavior. Instructions: ChessPiece Class: Properties: String color, boolean isAlive, int moveCount, Position position. Abstract Method: move(int x, int y). Position Class: Contains int x, int y. Tower Subclass: Extends ChessPiece. Overrides move for straight line movement. Deliverable: Source code for ChessPiece, Position, and Tower. Document class functionalities briefly.

Make sure you know the difference between an abstract class and an interface and constructors.

Abstract classes and interfaces may both be used to accomplish the goal of defining the behaviour of common objects.Which factors should you take into account when deciding whether to utilise an interface or an abstract class?

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?

-Interface IResearch Scholar has two methods public void teaches (String str) and public void studies (String str). - Define classes JuniorRS and SeniorRs such that JuniorRS implements IResearchScholar and SeniorRS extends JuniorRS. - Class InterAbstrTest extends SeniorRS, and has the main method. An object of JuniorRs invokes the method studies, and an object of SeniorRS invokes methods studies and teaches.

5. Is it compulsory for a class, which has been declared as abstract, to have at least one abstract method?

You need to perform following things to demonstrate the concept of abstract class. Step 1: Create the abstract class that has following methods. • Calculate the area of circle(Abstract method) • Calculate the area of triangle(Abstract method) • Calculate the area of rectangle(Method with implementation) Step 2: Create another class that extends above class and provide implementation of abstract methods. Step 3: Create the main method inside above class and display output of area of circle, area of triangle and area of rectangle. You need to submit the following things: • Java program with both the classes An output screenshot created using Microsoft Word
