OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
How many parameters must be passed if only the following prototype is given to a constructor?
Prototype: className(int x, int y, int z=0);
i) 1
ii) 2
iii) 3
iv) Compile time error
Step by step

- 5. How many parameters must be passed if only the following prototype is given to a constructor? Prototype: className(int x, int y, int z=0); a) 1 b) 2 c) 3 d) Compile time errorHow many parameters must be passed if only the following prototype is given to a constructor?Prototype: className(int x, int y, int z=0); 1 2 3 Compile time errorLanguage: C++ Next a thirst level (as double value) should be added to the properties of a critter. Add a new constructor that takes five parameters for setting all properties of a critter. Make also sure that the existing constructors will still work. For the existing constructors, the thirst level should be set to the same level as the hunger level. Your existing testcritter.cpp must still be able to run in its unchanged form. So the already existing constructors need to support the change. Name the files Critter.h, Critter.cpp and testcritter.cpp. Finally, you should adapt the print method for printing on the screen also the value of the thirst level as a double. The client program testcritter.cpp may contain one additional line, where the constructor taking five parameters is being called. You can assume that the setting values are always valid.
- It is possible for a class to have more than one constructor.A) This is correct. B) The answer is False.There are two types of data members in a class: static and non-static. Provide an example of when it might be useful to have a static data member in the actual world.Why is a class's destructor implementation required?
- What is the difference between a class's static data member and a non-static data member?Give an example of why a static data member would be useful in the real world.- Simple factory is not considered a design pattern because it does not decouple the client from concrete classes Select one: True False 2- structural patterns provide guidance on the way in which classes interact to distribute responsibility Select one: True False 3- The Simple factory is used when you want to limit the instantiation of classes to one implementation Select one: True False 4- When a class A is composing a reference to another class B, then we say that class A has-a class B relationship Select one: True FalseObject Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is…
- 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.What exactly are a class's "static members"? When and how can you make advantage of them?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…
