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.
This is the question -
Create an abstract NewspaperSubscription class with fields for the subscriber name, address, and rate. Include get and set methods for the name field and get methods for the address and subscription rate; the setAddress() method is abstract.
Create two subclasses named PhysicalNewspaperSubscription and OnlineNewspaperSubscription. The parameter for the setAddress() method of the PhysicalNewspaperSubscription class must contain at least one digit; otherwise, an error message is displayed and the subscription rate is set to 0. If the address is valid, the subscription rate is assigned $15. The parameter for the setAddress() method of the OnlineNewspaperSubscription class must contain an at sign (@) or an error message is displayed. If the address is valid, the subscription rate is assigned $9.

- Create a class - Car, to contain all the properties a car must have, color, brand, and model. then create an instance of a Car type object to represent my specific car. then set the value of the properties defined in the class to describe my car, without affecting other objects or the class template. then reuse this class to represent any number of cars.arrow_forwardWhich (if any) of the following conditions are necessary for using polymorphism? Select all correct answers. The classes involved are in the same hierarchy. None of the classes can be abstract. All of the subclasses involved override the same method. The object reference cannot be of an interface type. An object reference of the superclass is used to call any methods. A superclass object is referenced by a subclass reference. Which of the following (if any) are true of abstract methods? Select all correct answers. Abstract methods must have a method body. Abstract methods cannot be declared in a class that isn't abstract itself. Abstract methods cannot be private or static. Abstract methods can only be declared in an interface. Abstract methods cannot be called. Constructor methods can be abstract.arrow_forwardWhat does the super keyword represents and where can it be used? Give an example of a superclass and subclass. Be sure to make all the instances variables of the super class private. Include at least one constructor in each class and ensure that the constructor of the subclass calls the constructor of the superclass. Also include a toString method in both classes that returns the values of the instance variables with appropriate labels. Ensure that the toString method of subclass calls the toString method of the superclass so that the string returned contains the values of all the inherited instance variables.arrow_forward
