- Shape Classes Design classes Square, RightTriangle , and Triangle that encapsulate three geometric shapes. Each class should implement a method void draw (int x, int y) that “draws" a square, a right triangle, or an equilateral triangle (a triangle with three equal sides), respectively. See Figure 2. The parameters x and y specify the relative position of the figure: y lines down and x spaces acro from the current position of the screen cursor. The instance variables of each class are: int rows , the number of rows that comprise the figure, and char character , the keyboard character used for drawing the figure. Each shape of Figure 2 consists of five rows. The drawing characters are *** for the square, %' for the right triangle, and #' for the equilateral triangle. Shape (abstract) int rows char character Shape() Shape(int x, char c) int get rows() char getCharacter() void setRows(int x) void setCharacter(int x) void draw(int x, int y) (abstract) Square() Square(int x, char ch) void…5 points Save Answer QUESTION 4 What is printed? public class Puppy { private int puppyAge; private String puppyName; Puppy(String name){ puppyName = name ;} public void setAge( int age ) { puppyAge = ++age; } public int getAge(){ return puppyAge; } %3D public class TestPuppy{ public static void main(String []args) { Puppy myPuppy = new Puppy( "tommy" ); myPuppy.setAge( 2 ); System.out.print("Puppy's age is :" + myPuppy.getAge()); System.out.print(" %3D Name chosen is :" + myPuppy.puppyNname ); D Puppy's age is : 2 Name chosen is : tommy Puppy's age is : 3 Name chosen is : tommy O Syntax Error O Run Time Error Save All Answers Close Window Save and Submit - Save and Submit to save and submit.

Procedure: Develop a simple program that stores a patient's blood Create two (2) classes named BloodData (no class modifier) and RunBloodData (public). For the BloodData class: declare two (2) static String fields named bloodType for accepting (O, A, B, and AB) and rhFactor (stands for Rhesus factor, an inherited protein found on the surface of red blood cells) for accepting + and -. For the default constructor (public) of the BloodData class, set bloodType to "O" and rhFactor to '+'. Create an overloaded constructor (public) with two (2) String parameters: bt and rh. In this constructor, bloodType should store bt while rhFactor should store rh. Create a public method named display. This method will be used to display the values of bloodType and rhFactor. In the RunBloodData class, import the Scanner class for the user input. In the main…add override display methodusing System; //base classclass Book{//data membersprivate string title;private string author;protected double price;//constructorpublic Book(string t, string a){title = t;author = a;price = 500;}//method to display detailspublic void display(){Console.WriteLine("Title:" + title + " author:" + author + " price:" + price);}} //child classclass PopularBooks : Book {//constructorpublic PopularBooks(string t, string a) :base(t,a) {price = 50000;}} class Program {static void Main() {//an array of 5 objectsBook[] B = new Book[5];//input title and authorfor(int i=0; i<5;i++){Console.Write("Input title: ");string name = Console.ReadLine();Console.Write("Input author name: ");string author = Console.ReadLine();//if author is popular,//call constructor of sub classif (author.Equals("Khaled Hosseini") || author.Equals("Oscar Wilde") || author.Equals("Rembrandt")){B[i] = new PopularBooks(name, author);}//call base class constructorelse B[i] = new Book(name,…
