Part 3- Abstract classes Create a new Java project called firstName_lastName_Part3 in any platform online/offline. Select the option to create a main method. Create a new class called Laptop. Create a second new class called Computer.Rewrite your code from Part2 so that: The Computer class is abstract. The Computer contains at least one abstract method All methods, constructors etc that were in the Laptop and Computer classes in part 2 must be included in part 3. You need to rewrite the Laptop and Computer classes from part 2 so that Computer is abstract and there are multiple ways to create a Laptop. Check your code works by creating a new onton in your main method

Part 1: Setting the turtle size when it is instantiated Currently, a turtle is created and given a default size of 50. To change the size of the turtle its increaseTurtleSizeBy10 and decreaseTurtleSizeBy10 methods can be called. Add functionality so that a turtle can be created with a specified size. In the DoodleTurtle class do the following: Overload the DoodleTurtle constructor by creating a one-parameter constructor that takes the size of the turtle as an integer. Add an empty method body. Complete the method specification for the new constructor. The default constructor method specification can be used as a model. The only difference will be that the getTurtleSize() will equal the name of the size parameter instead of INITIAL_SIZE. In the method body of the one-parameter constructor do the following in this order: Call the initializeWithDefaultValues helper method. Call the setSize method passing it the size parameter. Compile the program and fix any…
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.
Create a super class university student with fields id, name and age . Define methods to read and print the details of students. Create a subclass engineering student with the fields gpa, specialization. Define the method to read gpa, specialization and another methods to find if the student in probation or NOT. Add a demo class to create an object for the subclass engineering student to read the details and to check for probation. In java language and only one code and work correctly.
This project utilizes three new classes: · Word - an immutable class representing a word · Words - a class representing a list of Word objects · WordTester - a class used to test the Word and Words classes. WordTester (the application) is complete and only requires uncommenting to test the Word and Words classes as they are completed. The needed imports, class headings, method headings, and block comments are provided for the remaining classes. Javadocs are also provided for the Word and Words classes. Word The Word class represents a single word. It is immutable. You have been provided a skeleton for this class. Complete the Word class using the block comments, Javadocs, and the following instructions. 1. Add a String instance variable named word which will contain the word. 2. Complete the one parameter constructor to initialize the word instance variable. 3. Complete the getLength method to return the number of characters in the…
Develop a set of classes for a college to use in various student service andpersonnel applications. Classes you need to design include the following:• Person—A Person contains a first name, last name, street address, zip code,and phone number. The class also includes a method that sets each datafield, using a series of dialog boxes and a display method that displays all of aPerson’s information on a single line at the command line on the screen
Design a class called Stopwatch. The job of this class is to simulate a stopwatch. It should provide two methods: Start and Stop. We call the start method first, and the stop method next. Then we ask the stopwatch about the duration between start and stop. Duration should be a value in TimeSpan. Display the duration on the console. We should also be able to use a stopwatch multiple times. So we may start and stop it and then start and stop it again. Make sure the duration value each time is calculated properly. We should not be able to start a stopwatch twice in a row (because that may overwrite the initial start time). So the class should throw an InvalidOperationException if its started twice. 1
(1) Add an __init__ method to the Widget class below. Each object of type Widget should have an instance variable called name and an instance variable called cost that represents a cost in dollars; those values are passed in when an object of type Widget is initialized. (2) Add a method to class Widget called is_cheap that returns True if the cost is less than $10, and False otherwise. (3) Add proper doctrings along with two examples for each method. You may use the Sample Usage code given below in your work.
Create a class Person to represent a person according to the following requirements: A person has two attributes: id Add a constructer to initialize all the attributes to specific values. Add all setter and getter methods. Create a class Product to represent a product according to the following requirements: A product has four attributes: a reference number (can’t be changed) a price an owner (is a person) a shopName (is the same for all the products). Add a constructer without parameters to initialize all the attributes to default values (0 for numbers, "" for a string and null for object). Add a second constructer to initialize all the attributes to specific values. Use the keyword "this". Add the method changePrice that change the price of a product. The method must display an error message if the given price is negative. Add a static method changeShopName to change the shop name. Add all the getter methods. The method getOwner must return an owner. Create the class…
Test your newly created subclasses inside the same TestComputer program you previouslycreated: create two new Laptops and two new Desktops with the data of your choice. UsetoString() method to show all data fields (including the data fields in the super class and sub class)Hint: Make sure to avoid redundancy in your code – no fields implemented in the Parent Classshould be repeated/reimplemented/redefined in children. package project2;class Desktop extends Computer { private int width; private int height; public Desktop() { super(); width = height = 0; } public Desktop(String manufacturer, String diskSize, String manufacturingDate, int numberOfCores, int width, int height) { super(manufacturer, diskSize, manufacturingDate, numberOfCores); this.width = width; this.height = height; } public int getWidth() { return width; } public int getHeight() { return height; } public void setWidth(int width) {…

1. Create a class called Triangle that models triangles using three points (the vertices) for the x's and three points for the y's. The vertices will be of type double. It will have two constructors: one by default and one that creates a triangle from its three vertices. The class will also include a method to calculate the area and another to calculate the perimeter of the triangle. Attributes are of type public. Write here the class diagram and class code in Java
Design a class named octopus that holds attributes for an octopus named weight and color. Include methods to set and get each of these attributes. Create the class diagram and write the class pseudocode that defines the class. Create a small program that declares two octopus objects and set the octopus's name weight and color attributes the program must also output each octopus's name weight and color after they are set. Please write out the pseudocode. I have a hard time with this.
