Step by step
Solved in 2 steps
- solve this question using only java object oriented programming, also you will need do use a 4 files in driver class ,d1 will help you to understand the realation between the classes, and d3 to know the function in index A you must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface:. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or any private methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media already received (rented) by the customer. There are twoplans a customer can have: UNLIMITED and…The following needs to be coded in java Thanks!! For this milestone, you will focus on delivering the appointment services. The purpose of these services is to add, update, and delete appointment objects within the application. The appointment service uses in-memory data structures to support storing appointments (no database required). In addition, there is no user interface for this milestone. You will verify the appointment service through JUnit tests. The appointment service contains an appointment object along with the appointment service. The requirements are outlined below. Appointment Class Requirements The appointment object shall have a required unique appointment ID string that cannot be longer than 10 characters. The appointment ID shall not be null and shall not be updatable. The appointment object shall have a required appointment Date field. The appointment Date field cannot be in the past. The appointment Date field shall not be null.Note: Use java.util.Date for the…This problem refers to this textbook question from chapter 4 https://www.bartleby.com/solution-answer/chapter-4-problem-3e-microsoft-visual-c-7th-edition/9781337102100/aaddcfdf-e049-11e9-8385-02ee952b546e I need help with the following question, its from Chapter 7, Exercise 7 for the following book Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (MindTap Course List) (p. 304). Cengage Learning. Kindle Edition. 7. In Chapter 4, you wrote a program named Admission for a college admissions office in which the user enters a numeric high school grade point average and an admission test score. The program displays Accept or Reject based on those values. Now, create a modified program named AdmissionModularized in which the grade point average and test score are passed to a method that returns a string containing Accept or Reject.
- The purpose of this exercise is to allow the student to demonstrate their understanding of application development, the creation and use of classes and objects in Python, and using the other tools (selection, iterations, functions, etc.) we have learned this term. We will make a simple game called 'Stray Cat Strut' - Using the grid class discussed in Chapter 9, create a 20 x 20 cell game board- This game board represents a backyard- Create a class called animal with two attributes:-- an attribute called 'location' which is a grid coordinate (e.g., B3)-- an attribute called 'lives' which is an integer.- The animal class has the standard methods (init, str, etc.) plus one additional method:-- a method called 'move' that changes the animal's location one cell up (N), one cell right (E), one cell down (S), or one cell left (W). - Extend the animal class to a subclass called cat, and another subclass called dog- cat inherits the animal attributes and methods, but also has the following…1. IntroductionCCCS 121Object Oriented Programming language Group Course ProjectAn object-based application is an application that involves objects created out of classes. These objects interact with each other to fulfill certain functionalities.The focus of this project is to develop an application written in java which involves the use of object-oriented programming. This project is a group project. As a student you will be given a chance to come up with an idea for your project. However, the project must satisfy the requirements given in this document.This document shall be used as a set of guidelines. You are allowed to make necessary additions and/or changes to the requirements with prior approval from your instructor.2. RequirementsPropose and implement an application, that contributes to solving a real-life problem. Your application should include at least the following:2.1 Classes3 to 4 classes each one of them should have:A. B. C.A number of private and public attributes. The…solve this question using java You must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface:. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or any private methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media already received (rented) by the customer. There are twoplans a customer can have: UNLIMITED and LIMITED. UNLIMITED allows a customer to receive as many mediaas they want; LIMITED restricts the media to a default value of 2 (this value can be change via a media rentalclass method).A movie has…
- In JavaScript, how are an object and an interface related to each other? a. The object’s interface consists of the code and data needed for that object. b. An object’s interface is analogous to a pocket calculator’s inner workings. c. Built-in JavaScript objects do not require an interface, but custom objects do. d. An interface allows another program to access an object’s properties and methods.You must develop Java applications using suitable coding and output.The following concepts must be included in you project: - Class- Object- Encapsulation- Inheritance- Overriding- Overloading- Polymorphism- I/O files- GUIThese are the minimum requirements for your project. Any additional concepts not mentioned in the above list can be used in your Java Applications.This application is to be developed using: - Coding statements, and correct programming steps for your entire project application. - Output screenshots after executing those programming steps.1. Create a java project in NetBeans and name the project Hw01. 2. Design and implement a class named Account that contains: • A private int data field named id for the account (default 0).• A private double data field named balance for the account (default 0).• A private double data field named annualInterestRate that stores the current interest rate (default 0). Assume all accounts have the same interest rate.• A private Date data field named dateCreated that stores the date when the account was created.• A no-arg constructor that creates a default account.• A constructor that creates an account with the specified id and initial balance.• The accessor and mutator methods for id, balance, and annualInterestRate.• The accessor method for dateCreated.• A method named getMonthlyInterestRate() that returns the monthly interest rate. (Hint: Monthly interest rate is annualInterestRate/12.)• A method named getMonthlyInterest() that returns the monthly interest. (Hint: Monthly interest is…
