THIS NEEDS TO BE DONE IN C#! Modify the code below so that the base class is an abstract class. class Pokemon{ protected string Name; protected string Type; protected string Health; public override void Attack() { //body of Attack } } Make Attack abstract as well.  You do NOT have to create a derived class.

PART ONE In C# create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing, Dancing, Musical instrument, and Other. Name these fields talentCodes and talentStrings respectively. The class contains an auto-implemented property Name that holds a contestant’s name. The class contains fields for a talent code (talentCode) and description (talent). The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue.cs program (See Program Below) so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this year’s competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value…

Inheritance, Polymorphism, ArrayLists, Throwing Exceptions The UML diagram below shows a set of classes designed to represent a music collection from 1995. The constructors and methods all function in the standard way, except: The equipmentRequired method should return “Record Player” or “CD Player” as appropriate.The getAlbum method of the NinetiesMusicCollection class accepts an index and returns the corresponding Album object. This method throws an IllegalArgumentException if the index is out of range. (This is the only exception you have to throw anywhere in your code.)In the NinetiesMusicCollection constructor, you can assume the ArrayList<Album> object passed as an argument is not null . Don’t worry about privacy leaks.Implement this set of classes in Java. Note the italics on the Class name “Album” and the method name “equipmentRequired” in the Album class.

in c++ Define another new class named “Item” that must inherit from the given Name class. This Item class will manage the following info: name (string) and price (double). It must prevent the creation of an Item object with either an empty or all-blank name. This class must at least complete the methods defined in the Name class: toString method returns a string representation of the Item object in the format of “ITEM( <name> ) PRICE($ <price> ) such as ITEM(eraser) PRICE($1.05) contains method that accepts a search string and returns true if only the name of the item contains the search string as a substring. It returns false otherwise. isTheSame method that compares two Item objects and returns true only if both Item objects have the exact same name (regardless of the price) and false otherwise. Please note that if the given object in the parameter is not an Item object, it will return false.

Modify and rewrite the Food class to an abstract class, so that no instance of Food class can be created

Why might a class need to implement a destructor?

Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works.  Next add the following public methods to the Address class and test them from main as you go: Write getters and…
