- Define a default constructor that initializes the data members, string title and integer year, with the default values "Empty" and -1, respectively. Ex: If the input is Magnolia 1989, then the output is: Title: Empty, Year: -1 Title: Magnolia, Year: 1989 Note: The class's print function is called first after the default constructor, then again after the inputs are passed to the setters. 5 class Book { 6 public: 7 8 9 10 11 12 13 14 15 }; 16 Book(); void SetTitle(string bookTitle); void Set Year (int bookYear); void Print (); private: string title; int year; 17 Your code goes here */ 18 19 void Book::SetTitle(string hook Title) { CS Scarint (19 bi Title mscanner 22 23 void Book Set Year(int bookYear) [ 2Software Requirements: • Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. our progras from rhFactor non-static and private. Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() getRhFactor() 3. Use the setter methods to accept user input. 4. Display the values by calling the getter methods. Sample Output: Enter blood type of patient: Enter the Rhesus factor (+ or -): O+ is added to the blood bank. Enter blood type of patient: B Enter the Rhesus factor (+ or -): B- is added to the blood bank.Java Programming Object-Oriented Programming In an abstract class, write a factory method for creating a category of object of your choice (aside from furniture).

Create an Employee class and use the provided UML diagram to code the instance fields, constructors and methods. 3.1.1 Both constructors must increment the static numberOfEmp field by one. Both constructors must call the setEmpCode() method to compile a code for the employee. Both constructors must call the setCommission() method. 3.1.2 setEmpCode() method: The empCode must be constructed in the following way: First character is the type of contract Next three characters a random 3 digits Add a backslash and the number of objects value to the code NOTE: You have to use the Random class in your code (See Ch 9). Do NOT use the Math.random() method. Example of code: S781/1 Explanation: Short term contracts (S), 781 is the 3-digit random value, first employee object. 3.1.3 setCommission() method: Assign a basic amount to the…
