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:
Step by step
Solved in 3 steps
- Write the abstract super class Transaction, and two of its subclasses, Payment and Sale (you do not need to supply any comments other than your name). I. Write an abstract superclass encapsulating a Transaction: The Transaction super class has an instance variable representing the customers name, and 3 methods: an overloaded constructor, a toString() method that returns a message including the name of the customer, and an abstract method called calculateAmount()which will be implemented in your subclasses. II. Write a non-abstract subclass that inherits from the Transaction class encapsulating a Payment: The Payment class has instance variable representing the payment amount received and 3 methods. It has an overloaded constructor, a toString() method that returns a message including customers name, the name of the class Payment, and the payment amount, an non-abstract class called calculateAmount() which returns the payment amount. III. Write a second…In the following there are two classes, Employee and Manager. Manager is a subclass of Employee. The implementation of Employee class is given (Note: no getter methods are provided, so you are not able to access instance variables through getter methods in the subclass). The skeleton of the Manager class definition is given. Complete the constructor method, and the toString method for the subclass (see the details below). public class Employee { private String name; private double salary; // Make an employee with a given name and salary. public Employee(String aName, double aSalary) { name = aName; salary = aSalary; } // Provide a string description of an employee. public String toString() { return "Name: " + name + "\tSalary: " + salary; } } public class Manager extends Employee { private String department; // Make a manager with a given name, salary, and department. public Manager(String name, double salary, String department) { // put your code below } // Provide a string…B and C are its subclasses, and A is the parent class. Now, B and C have certain similar features and methods, but B and C implement a number of their methods very differently. Use logic to specify if A is a concrete class, an abstract class, or an interface.
- An employee has a name, phone number and salary. A coach is a person with a senitority status, one of: junior, lead, and senior. Define the possible status values as constants. A staff is a person with a job title and job descrption. Your programming task is to Implement as abstract class named Employee and two subclass name Coach and Staff in Java as defined above Provide constructors for classes to initalize private variable Override the toString() method in each of the classes in task 1 to display the class name and the person's name Write an application to create objects of type Coach and Staff and print the person's name and the class name of the objectswhen an object of a subclass is instantiated, a superclass constructor Is called simplicity or explicitly true or false?You have a method which requires an argument of type superclass. It will function if you supply a subclass object rather than a superclass object. Is it permissible? What is the purpose?
- Create a subclass of the Employee class from Question 2 named ShiftSupervisor. Add the salary and bonus attributes to it, and override_init_and_str_accordingly. Add the appropriate accessor and mutator methods and check the functionality by prompting a user to input the data for a Shift Supervisor object. Use_str__ to print the result.Declare a superclass and subclass. Override a method of superclass in subclass and call thesuperclass’s constructor from the subclass with proper java syntax.All of the abstract methods of the parent class must be implemented by any subclass. Do you think it's right or wrong?
- JAVA Write the abstract super class Transaction, and two of its subclasses, Payment and Sale (you do not need to supply any comments other than your name). I. Write an abstract superclass encapsulating a Transaction: The Transaction super class has an instance variable representing the customers name, and 3 methods: an overloaded constructor, a toString() method that returns a message including the name of the customer, and an abstract method called calculateAmount()which will be implemented in your subclasses. II. Write a non-abstract subclass that inherits from the Transaction class encapsulating a Payment: The Payment class has instance variable representing the payment amount received and 3 methods. It has an overloaded constructor, a toString() method that returns a message including customers name, the name of the class Payment, and the payment amount, an non-abstract class called calculateAmount() which returns the payment amount. III. Write a…If class A is a subclass of class B, then A has access to all of B's instance variables, including private ones. True FalseWrite a class named Person with data attributes for a person’s name, address, and telephone number. Next, write a class named Customer that is a subclass of the Person class. The Customer class should have a data attribute for a customer number and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Demonstratean instance of the Customer class in a simple program.
