Write all code for a class Guitar as described here. A Guitaz can be described as having a number of strings (int), manufacturer (string), and price. Include the following methods in your dass definition • A default constructor. • An overloaded constructor which takes the number of strings and manufacturer as input. • A getter (accessor) method to acquire the price. • A tostring method that returns a reasonable description of the guitar. public class Guitar Write all the code necessary for a class TestGuitar as described here. TestGuitar implements a main method with the following functionality. i a) Construct one guitar object using the default constructor. b) Construct a second guitar object for a 6-string Gibson. c) Declare a variable p and initialize it with the price of the first guitar by calling the proper method. d) Print both guitar objects that were constructed. public class TestGuitar

Create a class Animal Create a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal (String name) //constructor public void makes Sound () with the implementation printing out a generic animal sound. Next, override (add) the makes Sound() method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don't make sounds!) Note, you'll also need a constructor in each of your subclasses which calls super(name) to initialize the common 'name' member of Animal. Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. (you should observe the makeSound method called will be: cat -> from Cat class, dog-> from Dog class, bearded Dragon -> from Animal class ) EC:…

Complete the code for the following program. You are provided with an abstract class called abst. Create a class that will be a child of abst and it will be called usesAbst. Your program will have an int variable called value, and all the appropriate methods, as well 2 constructors. The first constructor will simply set the variable value to 0. The second constructor will set the variable value to equal a passed in parameter. You do not have to comment your code. public abstract class abst{ public abst () { } //Outputs to the screen the message Hello public abstract void sayHello (); //returns the stored int value public abstract int getValue (); //sets the int value to x public abstract void setValue (int x); //Outputs to the screen the message Another method public void output () { System.out.println("Another method"); public String tostring () { return "This is an abstract class"; }

The total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…
Design a console program that will print details of DVDs available to buy. Make use of an abstract class DVD with variables that will store the title, yearReleased, running time and price of a DVD. Create a constructor that accepts the title, yearReleased and running time through parameters and assign these to the class variables. Create an abstract set method for the price of a DVD; also create get methods for the variables.Create a subclass InstructionalDVD that extends the DVD class and implements an iPrintable interface. The interface that must be added is shown below:public interface iPrintable { String ShowDetails();}The InstructionalDVD subclass has a private variable named category for which a get method must be written. The constructor of the InstructionalDVD class must accept the title, yearReleased, running time and category through parameters. Write the code for the setPrice() and ShowDetails() methods.Write a useDVD class and instantiate 2 objects of the InstructionalDVD…
Write a class definition line and a one line docstring for the class Dog. Write an __init__ method for the class Dog that gives each dog its own name and breed. Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbee
