- 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…Which of the following statements are true. a) An abstract method contains a signature but no code implementation. b) We cannot create an instance of an abstract class by using the new operator. c) We can derive classes from an abstract class, but we must provide code to implement all of the abstract methods. d) All of the above statements are true.Can we declare a class as Abstract without having any abstract method?
- Change the classes "Line" and "Matrix" as follows: a. all static properties of classes should be changed only inside class methods; b. select one or more sub methods (if it has not been done before) and arrange them as static methods.Note: Write a Java program given below Question # 1: Define a class for Students with field name, age, marks. Define getter and setter for all the fields. In the setter method, if age is less than 0, print that Age is less than zero. Similarly, if marks is less than zero or greater than 100, print in correct marks and don’t assign marks to member variable. In the Test class, create student’s object and assign the marks and age to appropriate values. Try assigning incorrect values to check if getter and setter methods work as expected.Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…
- For each statement, indicate if it is True or False by circling T or F. If you need to cross out an answer, be sure that your final answer is clear and unambigous-otherwise it will receive no credit. 1- An object of a derived class has access to the public methods of its base class T F 2- An object of a base class has access to the private helper methods of its derived class T F 3- Destructors are not inherited by derived classes T F T F T F u- An object of a derived class inherits the copy constructor of its base class 5- Operators are passed down inheritance hierarchies 6- Destructors in derived classes are called after their base class calls its destructor 7. Constructors of base classes are accessible by derived classes T T F FCreate a class BeautyProduct with name, color, brand. Provide Constructors, getters, setters and also write toString method. Now create a class Lipstick which extends the class BeautyProduct as Lipstick is-a Beauty Product it has totalVolume, remainingVolume, price, texture (gloss, matt) as private data members. Provide Constructors, getters, setters and an apply() method whenever this method is called a beauty item is applied and its volume decreases by 10.This should also check that volume must not be zero if it then u have to throw exception. Also write toString method which prints all details like name, color, brand, price, texture and volume. Create another class foundation having totalVolume, remainingVolume, price, texture (liquid, cake) and lastingTime (number of hours foundation remain intact on face and does not crease) as private data members. This also extends the base class i.e. BeautyProduct. Provide Constructors, getters, setters and an apply() method whenever this…Every employee in a firm XYZ has attributes employeeid, name and salary. However the sales employees in firm XYZ has all the attributes of employees and also has an additional attribute named bonus. You are a software developer who has to the implement the relation between employee and sales employee. Write the code for classes employee and employee_sales. Write the constructors for both classes that set the attributes of both classes.
- Assume a Pet class contains a declaration for a method called getName () that returns a String. Later, we do this: public class Dog extends Pet{ .. How would we go about overriding this method in the new class? O We can only override this method if it is abstract in the Pet class O We must declare a method in the new class with the same method name and parameter list O We must first use the super () constructor to ensure that the name has a value O We must declare a method in the new class with the same method name and return typeFor the Faculty class, create the following: A private int instance variable m_salary. A constructor that takes three parameters (in the order of name, department, salary). It should use the parameter for salary to set the m salary instance variable and then explicitly call the parent class constructor using the super keyword and pass in the two other parameters. A getPaycheck method that implements the same method in the Employee class. It returns the faculty member's paycheck as a string in the following format (the amount of money is equal to m_salary): Pooh-Mathematics-$50000Design and implement a Restaurant class with at least three meaningful attributes and two methods. Implement a test program which creates at least two instances of the restaurant class and calls all the methods. Some possible attributes are name, numberOfTables, cuisine, numberOfReservations, capacity, etc. Some possible methods are make Reservation, checkAvailability, etc. Note the following: -All properties must be declared as private and you need accessor and mutator methods for each property. - You need to define at least one constructor. Documentation o Include header comments that include description of the program. o Include body comments o Consistent indentations o Consistent white line spaces Properties are declared as private o Accessor and mutator methods are created o At least one default constructor o At least two instances are created
