- 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…In Java Your uncle is trying to keep track of his new-car and used-car lots by writing a Java program. Heneeds your help in setting up his classes.Implement a superclass named Car that contains a price instance variable, a getPrice method, anda 1-parameter constructor. The getPrice method is a simple accessor method that returns the priceinstance variable’s value. The 1-parameter constructor receives a cost parameter and assigns avalue to the price instance variable based on this formula:price = cost * 2;Implement two classes named NewCar and UsedCar; they are both derived from the Carsuperclass. NewCar should contain a color instance variable (the car’s color). UsedCar shouldcontain a mileage instance variable (the car’s odometer reading). The NewCar and UsedCarclasses should each contain a 2-parameter constructor, an equals method, and a toString() method.In the interest of elegance and maintainability, don’t forget to have your subclass constructors callyour superclass constructors…Write a class named Vehicle with vehicleType, manufactureYear(int) and cost(double) as private data fields. [Hint: VehcleType could be "truck", "4WD", "Bus"] . Add a constructor with any two parameters of the superclass. Write a class named Car which inherits the Vehicle class. Add a non-static private string variable called companyName. Add a constructor in the subclass and a toString() method that prints the Car's data fields in the order VehicleType, manufactureYear, companyName [Hint: Add a toString( ) method in the superclass as well]. Create objects of Vehicle and Car class. Can the object of Vehicle class be stored in an object of Car Class? If yes, write the code. If No, Explain why? ***Student Instruction *** You need to write the complete code as mentioned below: i) The main class with necessary codes. ii) The subclass with necessary codes.iii) The Test class with necessary codes.
- Write a java program in which Animal:Create a class Animal and Add a protected data member named id of integer type.• Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0.• Also provide parameterized constructor and toString method.• Add an abstract method tellAboutSelf method to Animal class with public access• Add another abstract method speak method to Animal class.Reptile, Bird, MammalNext create the three child classes which extends form Animal class.• Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”.• Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the…In java Create an abstract super class called Employee with the following attributes: name : String and the following methods getter and setter for the one attribute three constructors an abstract method called getSalary() equals() toString() Create a sub class of Employee called Faculty with the following attribute yearlyPay : double department: String and the following methods getter and setter for the attributes three constructors getSalary() that returns the yearlyPay divided by 52 equals() toString() Create a sub class of Employee called Staff with the following attributes: hoursWorked : double payrate : double and the following methods getters and setters for the two attributes three constructors getSalary() that returns the weekly pay (multiply hoursWorked by payrate, overtime included and 1.5 times payrate for hours > 40) equals() toString() Create a sub class of Employee called Sales with the following attributes: salesAmount : double //sales per week…Code a subclass named ExpressCard that inherits from the superclass CreditCard, which has two private data members: foreignFeeRate of double type, and domesticBonusMileageRate of double type Provide: default constructor with no parameters, constructor with all parameters to initialize its own private data and the inherited data from CreditCard getter/setter methods for each data member There are two effector methods: Method calcFee() takes no parameters and it returns double type. This method calculates the transaction fee. First you need to call the method in superclass to obtain the basic fee, and then for ExpressCard user, there is an extra charge for foreign spending. Given the same example above as in class CreditCard, the basic fee is $3, and under a foreignFeeRate of 3%, then the extra fee is calculated by multiplying $50 of foreign spending with 3% (0.03) of foreignFeeRate, which yields $50 *0.03 = $1.5, so the total fee is $3 + $1.5 = $4.5. Method calcMileage() takes no…
- Write a Java class Person for dealing with persons. Your class must have the following features: Person id: long name: String gender: String + Person() + Person (id: long, name: String, gender: String) + Create setter and getter for all data fields. + Override toString() method: you have to return required data Fields values. Constructor: public Person(): A default constructor, should initialize the data fields to their default values. public Person (SSN: long, name: String, gender: String): A constructor with parameters, that creates the person object by setting specified parameters.
