Expert Solution & Answer
Chapter 1, Problem 15E
Explanation of Solution
Declaration “derivedClass” follows “genClass”:
- Declaration of “derivedClass” class follows “genClass”.
- The “genClass” would act as base class and “derivedClass” acts as subclass.
- A base class is declared so that its member data instances could be shared with any of other inclusions of same base in further derived classes.
- The technique used is termed as virtual inheritance.
- The functions in base class could be used by derived classes.
Refer question 15 from chapter 1 for given declarations.
Member function invocation:
- The function “process1()” in “derived Class” contains integer parameters, the function declaration is hidden in “genClass”...

Why is it necessary to put in additional effort and code in Java programming (or object-oriented programming in general) in order to prevent having classes that are unnecessarily linked? Give three essential grounds for your position.
Part – 3 (Abstract Class and Interface)
Consider the Class that you designed in Part#1 of this project and do the following:1. Implement the Comparable and Cloneable interface for your class.2. The Test class should create 5 instances (objects) of your class.3. Store these instances in Array and ArrayList4. Show the demo of sorting these objects stored in Array and ArrayList
Include the below in your project report:
1. Screenshot of relevant (Comparable and Cloneable) outputs.2. Code for all classes.
part1:
Part 1)
CODE
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
class Person {
private String fName;
private String lName;
private String gender;
private boolean isHungry;
public Person() {
fName = "John";
lName = "Doe";
gender = "Male";
isHungry = false;
}
public Person(String fName, String lName, String gender, boolean isHungry) {
this.fName = fName;
this.lName = lName;…
1. In Java a class can only directly inherit for a single parent class. Explain why this is not a limitation. Give an example
2. What would be an example of overriding a method? In terms of inheritance, why is it important to be able to override a method?
3. Consider the following Java classes. Assuming that all of these classes are in the same directory. What will be the output when TestClassC is compiled and run.

- What are the advantages of interfaces?Why not just instanciate class objects directly?arrow_forwardWrite a Java program that implements parallel programming using the Fork/Join framework. Step1- The program should initially generate 15 million random numbers. This should be read into an array of doubles. Step 2- Then it should make use of a method that uses this array to calculate the sum of these doubles. Step 3-This program should make use of the subclasses in the Fork/Join Framework. it must also output the number of processors available. Lastly, Have a clear screenshoot of code in the IDE and a screenshot of the code running.arrow_forwardWhy would you want to define a virtual destructor?arrow_forward
- When comparing abstract classes and interfaces, what are the main differences?arrow_forwardWhy is it essential to spend extra effort and code in java programming (or object-oriented programming in general) to avoid excessively linked classes? Give three fundamental reasons.arrow_forwardAssume you have a method that needs an object of the superclass as an argument. In this situation, you should provide it with a subclass object rather than a superclass object. Is it appropriate? Why do you believe that?arrow_forward
- What are the most notable differences between abstract classes and interfaces?arrow_forward1) Final, Static and Interface keywords. (a) Briefly discuss how final prefix is used on attribute, method, and class in order to build a library of security related functions. (b) Discuss the two (2) differences between an interface method and an abstract method, and provide example of an interface with a single method using Java code segment. (c) Briefly discuss how static prefix is used on attribute, method, and class in order to build a library of mathematics functions. 2. Generics, Exceptions and Parameters. (a) Create a simple Java program to demonstrate the use of exception handling in Java OOP programming. (b) Briefly discuss the use of generic type in Java. (c) Briefly discuss the differences between argument “pass by value” and “pass by reference” parameter. Create a simple Java program to demonstrate pass by value argument.arrow_forward1. Creating overloaded methods with identical sets of parameters and different return types result in compilation errors. Overloaded methods must have different sets of parameters- also known as signatures. Is it True or False? 2. Attempting to modify a final instance variable after it is initialized is a compilation error. Is it True or False? 3. A subclass can effect state changes in superclass private members only through public, protected methods provided in the superclass and inherited into the subclass. Is it True or False?arrow_forward
- Why are interfaces beneficial, exactly? Is it not simpler to just make instances of a class?arrow_forward1 You have studied encapsulation and inheritance that are two important concepts of Object- Oriented Programmin and write a program of your own choice in it that can explain these concepts, and in the context of that program.And Also write the main method that can test the classes. write your answer below that will explain 1. How encapsulation and inheritance was achieved in this program? 2. What are the benefits you get after implementing encapsulation and inheritance in this program? 3. What are the disadvantages if you will not use encapsulation and inheritance in this program?arrow_forward// The language is java What, Why, and How to code inheritance? How can you access private instance data in a super class from a subclass? What is purpose to override toString() method? Use of coding examples to explain your answer.arrow_forward
