Consider this situation: We want to create classes to model coordinates in 2D space and 3D space. For example, a 3D coordinate object will represent a single point in 3D space, and collections of these points can form a shape or function. These classes will be reused in a variety of mathematical programs, some of which will require 2D coordinate objects and others which require 3D coordinate objects. We will not be making graphs of any other dimensions. We decide that the 3D coordinate class should inherit its functionality from the 2D coordinate class. Based on the description for how it will be used, should the 2D coordinate class be a concrete class, abstract class, or interface? O Interface Concrete class O Abstract class

Now we want to create an Object oriented System for a shopping mall. It has Items with name, manufacturer and price. Provide constructors. Getters, setters, toString methods. We add several items to Store. For that create a store class having name and arraylist of items, Provide Constructors, getters/setters and toString(), in addition you have to provide a method add which add new item to the array. The main function that does these things looks as follows: Public static void main(Strings[] args) { Item shampoo2(“pantene”, “Procter & Gamble”,100), noodles(“Noodles”, “knorr”, 50); // add further items. Store abcSuperStore; abcSuperStore.add(shampoo2); abcSuperStore.add(noodles); … abcSuperStore.sale(shampoo2); a bcSuperStore.sale(noodles);
Your task is to implement the Name class. This class represents a person's name. It has three instance variables representing the first, last and middle name (all are string variables). A character instance variable representing a separator (to be used for printing purposes) is also part of the class. The only valid separators we can have are a comma (,), a dash (-), and a pound symbol (#). In addition, a nickname instance variable (string) keeps track of the person's nickname (if any). The output have to match with the image I provided. Please don’t use chegg solution, need a different coding style. Write code in JavaScript

Implement the Solver class. In doing so, you are allowed to define other classes to help you (as well as use “built-in” Java classes or the book’s classes). The point of the solver class is the solve method which takes a board/puzzle configuration represented as a 2D array of booleans and returns a char array containing a minimal sequence of moves that will lead to the solved board (all the cells around the edges being filled). The board configuration is passed in as a 5-by-5 boolean array of Booleans with exactly 16 true cells (filled) and 9 false cells (empty). The solve method then returns an array of characters representing a minimal sequence of moves that solves the puzzle. In other words, if the characters from the returned array are used in order as input to the move method on the Board object representing the initial configuration, the resulting board configuration represents the solved board. Furthermore, the solution must be minimal in the sense that there are no solutions…

Write a Rectangle class. A Rectangle has properties of width and length. You construct a Rectangle object by providing the width and length in that order. If no width and length are provided to the constructor, construct a Rectangle with width 0.0 and length 0.0. We want to be able to get and set both the width and the length independently. We also want to be able to ask for the area of the rectangle and the perimeter of the rectangle. What will the object need to remember? width and length - those are the instance variables. Rectangle class has these constructors : public Rectangle() - Constructs a new rectangle with width and length of 0.0. public Rectangle(double width, double length) - Constructs a new rectangle with the given width and length. Remember that the job of the constructor is to initialize the instance variables. It has these methods. public double getWidth() - Gets the width of this Rectangle public double getLength() - Gets the length of this Rectangle public void…
In this task, you will create your own interface, which is not provided in the Java library. Let’s start with a simple example. Say we have a collection of animal classes, with each class represents a kind of animal. They all share a common ability of “speak”. Dog speak in the way of “Woof! Woof!”, cats speak in the way of “Meow! Meow!”, etc. In order to capture this common characteristic, we need an interface named Speakable: public interface Speakable { // put the method header here } Think about what method is needed for the Speakable interface? (what method can describe the speakable feature? ) We simply need one method speak() to print out the way that the animal “speaks”. Put the method header in the interface body. This method does not take any parameter and does not return any value. Be reminded that you only need to put the method header with a semicolon (abstract method) into the interface. BE NOTED: Adding an interface is different from adding a class. You need to click File…
When you add a contact to your phone, it automatically sorts those names alphabetically. In this exercise, we are going to create a phonebook that automatically sorts everytime a new number is added to the phonebook. A PhoneNumber class has been created already that has the instance variables name and number. Your job is to create the PhoneBook class that will store an ArrayList of PhoneNumbers. The PhoneBook class does not have a constructor - it only contains an ArrayList that can store the individual phone numbers that are added to it. There should be three methods in the PhoneBook class: addNumber- This method takes a PhoneNumber and adds it to the directory. Once the number has been added, the sort method is called on the directory to sort that new address into the phone book. sort- This method sorts the directory in alphabetical order A-Z.a. Remember that in order to compare Strings, we can use the compareTo() method. This returns an integer that indicates whether a String’s…
Define a Polygon interface that has methods area() and perimeter(). Then implement classes for Triangle, Quadrilateral, Pentagon, Hexagon, and Octagon, which implement this interface, with the obvious meanings for the area() and perimeter() methods. Also implement classes, IsoscelesTriangle, Equilateral- Triangle, Rectangle, and Square, which have the appropriate inheritance relationships. Finally, write a simple user interface, which allows users to create polygons of the various types, input their geometric dimensions, and then out- put their area and perimeter. For extra effort, allow users to input polygons by specifying their vertex coordinates and be able to test if two such polygons are similar ORIGINAL WORKS ONLY
In order to implement different ways of discount strategies for an object oriented parking system, we have a DiscountStrategy interface and CompactWeekendDiscounts class. The CompactWeekendDiscounts class class checks if the date is a weekend and the car we are about to park is compact and makes a discount. Based on the class diagram implement the two - a DiscountStrategy interface and CompactWeekendDiscounts class using java. (no need to implement ParkingLot class )
