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:
Declare an interface named Employee with the methods named sALARY and bEHAVIOR declare
a concrete class which will implements the methods of Employee (using java)
Step by step
Solved in 3 steps
- True or False A class can implement more than one interface.Design a Class Customerinsurance that implements Customer and Insurance interfaces, The Customer Class has the customers' details and abstract functions getoustomer().setCustomer(). The Insurance interface has the details of policy name, yearly premium amount and abstract functions get getpolicy(), Setpolicy() The Customer insurance class get the policy name payment type (quartery, hall yearly, yearly) of the customer and calculate the policy amount to be paid Write only in JavaAn interface is a collection of _______ that a class can implement
- Weite java code to implement given statements An abstract class must be declared with an abstract keyword.• It can have abstract and non-abstract methods.• It cannot be instantiated.• It can have constructors and static methods also.• It can have final methods which will force the subclass not to change the body of the method.Use the class diagram below to create a Parking Charge class for an object-oriented parking system. Write your code using java. Classes should contain properties and method implementations. N.B. Try to make your code readable.language: Java Class Inheritance with an abstract class Define a class Employee with the following fields: _name, _empId, _department, _position (_title), _yearlySalary, _fullTime (a boolean: true/false) , _month , _year (time of hire) Add constructor and properties Define an abstract method GetBiMonthlySalary() (if the employee is paid twice a month) Define an abstract method GetVacationTime() that returns the number of vacation time this employee would have based on time of hire Override the ToString() method to return a string that contains the information pertaining to an employee such as name, empId, department, and where full time or not. Define a class HourlyEmployee that inherits from Employee. This class should have 2 fields of its own: _hours (hours worked in half a month) and _wage (hourly wage) Provide necessary constructor, properties and methods Override the ToString() to also return the additional fields Gets 3 days of vacation after first year if the…
- Java Programming Create "Mammal" class as a parent class and "cat" as a child class Mammal(Superclass) Attributes name Methods move() eat() cat (Subclass) Attributes age Methods dispaly() eat() Override eat method in cat subclass. Print something in methods such as in move method you can print “I can move”. Test the inheritance with creating objects and calling parent and child methods. Create object of a child class by passing arguments to the constructor.True or False 1) After a user defines his/her own constructor in a Java class, the default constructor is still available. ___(2) Java supports multiple inheritances directly. ___(3) Some methods in an interface can have method body.True or False ___(1) An abstract class can have fields. ___(2) You can create an object from an abstract class _ _(3) An abstract class can have both abstract methods and methods that have method body
- Using C# - The following is an abstract class, which declares an abstract method named startEngine. Create a subclass of class Vehicle named Car that overrides the method startEngine by displaying the message: “Starting my car…." using Console methods.public abstract class Vehicle{ public abstract bool startEngine(); } Please provide code output screenshotDesign a console program that will print details of prescribed textbooks of students. Make use of an abstract class Book with variables that will store the author, title, category and price of a book. Create a constructor that accepts the author, title and category through parameters and assign these to the class variables. Create an abstract set method for the price of a book; also create get methods for the variables.Create a subclass TextBook that extends the Book class and implements an iPrintable interface. The interface that must be added is shown below:public interface iPrintable { String DisplayDetails();}The TextBook subclass has a private variable named yearPrescribed for which a get method must be written. The constructor of the TextBook class must accept the author, title, category and yearPrescribed through parameters. Write the code for the setPrice() and DisplayDetails() methods.Write a useBook class and instantiate 2 objects of the TextBook class.Use the class diagram below to create a money class for an object-oriented parking system. Write your code using java. Classes should contain properties and method implementations. N.B. Try to make your code readabale.
