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
Solved in 2 steps
- 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 errorTo implement an interface, a concrete class must implement AT LEAST ONE method headings listed in the definition of the interface. False. True.1) Change the visibility of the variables and constructor in the Employee class to be more secure 2) Add an Admin class with the following features: a) The Admin class is a child of the Employee class b) Admin objects have an instance string password variable c) The Admin class has a 4 parameter constructor. One parameter sets the string, the other three parameters are used as arguments for a parent constructor call. d) Admin objects have an instance getInformation() method with a void return and an Employee object parameter. The method will request the calling Admin’s password and check user input. If input matches the password, the method will display the information of the Employee parameter Please use ***C Sharp** Language to answer the code
- Design FullTimeEmployee class and PartTimeEmployee class which inherit Employee class so that the following code provides the expected output.[addFullTimeEmployee() and addPartTimeEmployee() methods should work any number of parameters assuming that the parameter number will be an even number and greater than 1]class Employee: total_employee = 0 def __init__(self, name, work_hour): self.name = name self.work_hour = work_hour def __str__(self): s = “Department: ”+self.name+", Work hours: "+str(self.work_hour) return s# Write your codes here.# Do not change the following lines of code.p1 = FullTimeEmployee(“Finance”, 40 )print("=================================")p1.addFullTimeEmployee(“Bob”, 12, “Carol”, 18, “Mike”, 15)print("=================================")print(p1)print("=================================")p2 = PartTimeEmployee(“Others”, 25)print("=================================")p2.addPartTimeEmployee(“David”, 12, “Simon”,…1. Write a java code for the above class diagram for “Car”.2. MAX_Weight must be a public class constant which is set to 6.4 3. The data member “counter” must be a class member and initialized to zero4. Use “counter” to assign a unique id for each class instance ( counter++ ) by the constructor5. The constructor is used to initialize all the instance variables by receiving the values from the user. Don’t change the parameter’s names.6. “convertMeterIntoMile” and “convertMileIntoMeter” are class methods:a. convertMeterIntoMile: convert the reading into miles by dividing the receiving value by 1.62b. convertMileIntoMeter: convert the reading into meter by multiplying the receiving value by 1.627. The method “computeFuelEconomy” must be overloaded and return a dummy calculation8. In the main method:a. Create an array of objects to hold five objects of class Car.b. Add them to the array. Note that the code for class Person is included but you need to import it from package “people”c. By…To implement an interface, a concrete class must implement AT LEAST ONE method heading.False.True.
- How many default constructors can a class have? a. A class cannot have a default constructor. b. only one c. as many as it needs d. one or more, but fewer than threeWhat method is automatically executed whenever a new instance of the class, which the method belongs to, has been instantiated? a. encapsulation b. abstraction c. polymorphismA class is a programming construct used to decouple an implementation's behavior from the information it needs to complete its work. Therefore, all types of data are accessible to functions and classes. an incorporated header file a phony technique Simple outline for creating classes
- a c++ program in which class A is base class for class B. While Class C is derived from class B and class D is derived from class E. Provide explicit implementation of default constructors and destructors. Write a test program which initializes each class object and shows execution order of constructor and destructor by printing appropriate messages. Modify the above classes and provide overloaded constructor implementation for each class. (Note: Use base initialize for this purpose) Note: Solve as soon as possible use oop conceptsUse java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
