CLASS NAME List the instance variables in the constructor. List the methods in the class. - indicates private CLASS NAME List the instance variables in the constructor. List the methods in the class. The second row of the UML diagram lists the instance variables in the constructor. For example -name: string o o name is the variable name o string is the data type of name + indicates public o getName is the method name o o string is the return data type Java.util. The third row of the diagram lists the methods in the class. For example, +getName(): string empty parenthesie indicate nothing is sent to the method.

Instructions: IMPORTANT: This is a continuation of the previous part of the project and assumes that you are starting with code that fulfills all requirements from that part of the project. Modify the your code from the previous part of the project to make it modular. In addition to the main method, your code must include the following static methods: Method 1 - displayTitle A method that creates a String object in memory to hold the text “Computer Hardware Graphics Quality Recommendation Tool” and displays it Method 2 – getResolutionString A method that accepts an integer value (1, 2, 3, or 4) that denotes the monitor resolution. The method should return the appropriate String representation of the monitor resolution. For example, if the method is passed an integer value of 1, it should return a String with a value of “1280 x 720”. (See Step 4 of Project 1) Method 3 – getMultiplierValue A method that accepts an integer value (1, 2, 3, or 4) that denotes the monitor resolution and…
Design and implement a class called Car that contains instance data that represents the company, price, model, and year of the car. Define the Car constructor to initialize these values. Include getter and setter methods for all instance data, and a toString method that returns a one-line description of the car. Create a driver class called CarTest, whose main method instantiates array of Car objects and write the following methods: 1) Method “printInfo” that receives an array of cars and returns all information about all cars. 2) A Method called getTopByCompany that receives an array of Cars and then returns an array of cars containing the cars that have the highest price compared with cars from the same company.
A cash processing company has a class called Account used to process transactions: Method/Constructor Description public Account (Client c) public boolean process (Transaction t) constaucts an account using client information processes the next transaction, returning true if transaction was approved, false otherwise Account objects interact with Transaction objects, which have many methods including: Method/Constructor Description returns the value of this transaction in pennies (could be negative, positive or zero) public int value() The company wishes to create a slight modification to the Account class that filters out zero-valued transactions. Design a new class called FilteredAccount whose instances can be used in place of an Account object but which include the extra behavior of not processing transactions with a value of 0. More specifically, the new class should indicate that a zero-valued transaction was approved but shouldn't call the process method in the Account class to…
Portfolio Instructions: You are working for a financial advisor who creates portfolios of financial securities for his clients. A portfolio is a conglomeration of various financial assets, such as stocks and bonds, that together create a balanced collection of investments. When the financial advisor makes a purchase of securities on behalf of a client, a single transaction can include multiple shares of stock or multiple bonds. It is your job to create an object-oriented application that will allow the financial advisor to maintain the portfolios for his/her clients. You will need to create several classes to maintain this information: Security, Stock, Bond, Portfolio, and Date. The characteristics of stocks and bonds in a portfolio are shown below: Stocks: Bonds: Purchase date (Date) Purchase date (Date) Purchase price (double)…
Design a Book class that holds the title, author’s name, and price of the book. Books’s constructor should initialize all of these data members except the price which is set to 500/-. Create a display method that displays all fields. All Books are priced at 500/- unless they are PopularBooks. The PopularBooks subclass replaces the Bookprice and sets each Book’s price to 50,000/- through PopularBooks construcor. Override the display method to display all fields. Write a Main () method that declares an array of five Book objects. Ask the user to enter the title and author for each of the 5 Books. Consider the Book to be a PopularBook if the author is one of the following: Khaled Hosseini, Oscar Wilde, or Rembrandt. Display the five Books’ details. c sharp
Defining Classes Write and document the definition for the Product class. Each Product object has three instance variables: description, productNumber and price. The class has one constructor that takes three parameters in the order productNumber, description and price. The class has one accessor method named getCost(int qty) which returns the price for qty items of the Product. The class has two mutator methods—setPrice() and setDescription()—that modify the corresponding instance variables. The class has a toString() method that returns the Product as a String in the form: 34567: Small Toaster, $ 17.95. Note: use concatenation to construct the returned string. Do not use the String.format() method to format the returned value.
Create an object called Circle. Declare the following integer variables for the object Circle, radius, diameter, ind pi is declared as double. Create the following for the Circle object: Implicit constructor (default constructor) Void method Calculate (double pi, int radius) to calculate the area of the Circle object. The method must include a system.out statement that displays the area value. Use the following formula to calculate area of the circle: Area = pi* (r* r) %3D our program includes a main class called Shape with a reference c1 to the Circle object. Pass the following alues to the object Circle: radius = 4 diameter = 8 pi = 3.14 nclude output statements to view the values passed to the object Circle.
