Software 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.
Using C# Language: Programming PLO 3 Measured: Create control structures, methods with the appropriate parameters, and data structures of the appropriate type, and implement algorithms to solve problems. Design a class named Contractor. The class should keep the following information: Contractor name Contractor number Contractor start date Write one or more constructors and the appropriate accessor and mutator functions for the class. Write another class named Subcontractor that is derived from the Contractor class. The Subcontractor class should have member variables to hold the following information: Shift (an integer) Hourly pay rate (a double) The work is divided between two shifts, a day shift, and a night shift. The shift variable will hold an integer value representing the shift that the subcontractor will work. The day shift is 1 and the night shift is 2. Write one or more constructors and the appropriate accessor functions for the class. Demonstrate the classes…

Class Implementation Exercises EX1: Write a complete C++ program to implement a car class. The class has three attributes: Id, speed and color. Also, the class include the following methods: (setter) function, (getter) function, (default and parameterized constructor), and( print) to print the attributes values ➜ Create three objects in the main function then call the method. EX2: Write a complete C++ program to implement a student class. ➜ The class has three attributes:std-Id, Name and marks [3]. Also, the class include the following methods: (setter) function,(getter) functions (default and parameterized constructor), (average) and(print) to print the attributes values ➜ Create array of objects in the main function then call the method.

The class definition for an Item is given in the image UML diagram below Note: getInfo() returns a string containing ALL of the state information neatly organized. Part 1: Create a class based on the specification above. Reminder: – means private and + means public. Part 2: a)Write a function/method called “addItem” that takes: An array of items The number of items in the array An integer representing a barcode A string representing the name of an item A string representing the description of an item A double value representing the price The function must create and add the item to the array if there is space. The function must return “true” if the addition was successful and “false” otherwise. b)Write a function/method called “listItems” that takes: An array of items The number of items in the array The function must return a string containing the information on each item in the array. c)Write a function called “pricelookup” that takes : An array of items The number of…
