- create methods that create and return something that can be output by a calling program. Maker sure to separate the processing (functionality) and presentation (user interface) into two separate java files. Write a recursive method that is passed a single int parameter, N, and create and return a String containing all the odd numbers between N and 0 in descending order. Subject: Java ProgrammingCreate a class ‘Box’ that has height, width and depth. The class should have a method volume() which shows the volume of the box. Now, create a driver file where you will create multiple Box objects with arbitrary dimensions and show their result. c++ 3. Create classes that capture bank customers and bank accounts. A customer has a first and last name. An account has a customer and a balance. Now, create a driver file where you will make objects for two accounts held by the same customer.c++Create a class SocialEvent with 3 attributes: Event title,date, for simplicity, we won’t restrict the date to a specific format andnumber of attendees..The class should contain a constructor (__init__ method), accessor and mutator methods (getters and setters), and a __str__ method.In the same file, write a main function that prompts the user to input 3 events. The function outputs the events sorted by number of attendees.
- Choose the correct answer for all of the following questions. You must highlight the correct answer. 1. The state of an object is described by its __________. a. Data Fields b. Constructor c. Constants d. MethodsDesign a class in python named Book that holds a stock number, author, title, price, and number of pages. Include methods to set and get the values for each data field. Also include a displayInfo() method that displays each of the Book's data fields with explanations.Design a class named TextBook that is a child class of Book. Include a new data field for the grade level of the book. Override the Book class displayInfo() method to accommodate the new grade-level field.True/False Questions. Circle the correct option. 1.T / F-A class protects the code inside it via inheritance. 2.T / F -PASCAL is used for scientific purposes and work is to be done in batches 3.T / F -In high level programming language Pascal, each program statement ends with the single quotation marks 4.T/ F-In unstructured programming language BASIC, program can be divided into the different procedures 5.T / F-'object program' is also called machine code 6.T / F -Type of program which can be run on different types of computer by making little changes into it is classified as fixed program 7.T / F -OOP paradigm was introduced in Ada with version Ada95. 8.T / F -A collateral command specifies that exactly twocommands may be executed in any order 9.T / F -PYTHON adopts reference semantics. This is especially significant for mutable values, which can be selectively updated 10.T / F-#Character = 256 (ISO LATIN character set)
- In java preferably eclipse Task: Create 2 Java classes Book BookDemo → contains the main() method Instructions: First create a class called Book The class Book DOES NOT HAVE a main method Create instance variables for: title: a String that contains the title of the book. author: a String that contains the name of the author publisher: a String that contains the name of the publishing house numCopiesSold: an int that holds the number of book copies sold. This must be a nonnegative value. yearOfRelease: an int that contains the year of the book's release. Only consider books released during 1950 – 2020. Create the Default Constructor – sets everything to default values and has no parameters. Create a Parameterized Constructor – with 5 parameters Create Accessors and Mutators for each instance variable MAKE SURE THE MUTATORS CHECK FOR VALID VALUES! Create the following Methods toString(): returns a String that contains the values of all instance variables for a particular Book object.…In an n-sided regular polygon, all sides havethe same length and all angles have the same degree (i.e., the polygon is both equilateraland equiangular). Design a class named RegularPolygon that contains:■■ A private int data field named n that defines the number of sides in the polygon with default value 3. ■■ A private double data field named side that stores the length of the side withdefault value 1.■■ A private double data field named x that defines the x-coordinate of the polygon’scenter with default value 0.■■ A private double data field named y that defines the y-coordinate of the polygon’scenter with default value 0.■■ A no-arg constructor that creates a regular polygon with default values.■■ A constructor that creates a regular polygon with the specified number of sidesand length of side, centered at (0, 0).■■ A constructor that creates a regular polygon with the specified number of sides,length of side, and x- and y-coordinates.■■ The accessor and mutator methods for all data…1.Question CREATE ANOTHER CLASS FOR TEAM The CODE FOR POKEMON: package com.company;import java.io.FileOutputStream;import java.io.IOException;import java.io.ObjectOutputStream;import java.io.Serializable;import java.util .*;public class Pokemaon implements Comparable, Serializable, Fightable {String name;int level;int health;int attack;String type;//2 Constructors - 1 Default, 1 sets all variablespublic Pokemaon(String name, int level, int health, int attack, String type) {super();this.name = name;this.level = level;this.health = health;this.attack = attack;this.type = type;}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getLevel() {return level;}public void setLevel(int level) {this.level = level;}public int getHealth() {return health;}public void setHealth(int health) {this.health = health;}public int getAttack() {return attack;}public void setAttack(int attack) {this.attack = attack;}public String getType() {return…
- Use Java Programming Language Create a Loan Account Hierarchy consisting of the following classes: LoanAccount, CarLoan, PrimaryMortgage , UnsecuredLoan, and Address. Each class should be in it's own .java file. The LoanAccount class consists of the following properties: principal- the original amount of the loan. annualInterestRate - the annual interest rate for the loan. It is not static as each loan can have it's own interest rate. months - the number of months in the term of the loan, i.e. the length of the loan. and the following methods: a constructor that takes the three properties as parameters. calculateMonthlyPayment() - takes no parameters and calculates the monthly payment using the same formula as Assignment 1. getters for the three property variables. toString() - displays the information about the principle, annualInterestRate, and months as shown in the example output below. The CarLoan class which is a subclass of the LoanAccount class and consists of the…Design a class named StopWatch. The class contains:■■ Private data fields startTime and endTime with getter methods.■■ A no-arg constructor that initializes startTime with the current time.■■ A method named start() that resets the startTime to the current time.■■ A method named stop() that sets the endTime to the current time.■■ A method named getElapsedTime() that returns the elapsed time for thestopwatch in milliseconds.Draw the UML diagram for the class then implement the class. Write a test programthat measures the execution time of sorting 100,000 numbers using selection sort.Create a text file in Java, then Write complete Java code to Write the following text to Text file “Java is an object-oriented programming language know" Finally, write Java code to read the text from the text file and display it on the jTextFields.
