Assignment:
Write the class XXXX_Worker with constructors, accessors, mutuators, and a toString
method. A Worker has a Worker Name and Number.
Write the class XXXX_ProductionWorker which is a subclass of Worker. The production worker has a shift number (values: 1 or 2) and an Hourly pay rate. A shift number of 1 means the day shift and 2 means the night shift.
Write the class XXXX_ShiftSupervisor which is a subclass of Worker. The shift supervisor is a salaried worker who supervises a shift. The shift supervisor has a yearly bonus field. The yearly bonus is earned at year end based on performance.
Write a class, XXXX_TestWorker, which does the following:
Creates one Shift Supervisor object from information entered by the user.
Creates an Array of Production Workers that can hold 3 objects.

3. Person and Customer Classes
The Person and Customer Classes Write 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. Demonstrate an instance of the Customer class in a simple program.

- In-class Assignment Day 8 You should draw the hierarchy for your classes to understand how the coding should be structured. Be sure to notate any classes that are abstract. Write an abstract class for Shape. The intended subclasses are Polygon, Circle, Triangle, and Rectangle. All of these will have a name, an area, and a perimeter. (Consider which methods might be abstract.) Add a toString method that will return the information about the Shape, for example: Triangle, Area: 7.5, Perimeter: 12.0 Write the class Rectangle. A Rectangle is a Shape and should have a width and a height. When a Rectangle is outputted, it should read: Rectangle, Length: #, Width: #, Area: #, Perimeter: # Write the class for Circle. Every circle is a Shape that has a radius. Be sure to provide an accessor method (getter) for the radius. When a circle is outputted, it should read: Circle, Radius: #, Area: #, Circumference: # Write a TestShape class that has the main method, which creates…arrow_forwardAn instance of an abstract class is made by using the keyword 'new'. true or falsearrow_forwardConsider the following class: public class theClass { private double value; private string str; public static int count; public theClass () { } public theClass (double d, int, x, String s) { } public void print() { } public static void incrementCount() { } } a) How many members do class theClass have? b) Compare the purpose of the two constructors. c) Use the reference this to write the definition of a method print( )to output the value of the instance data members separated by commas. d) Write a statement to create an object myClass of the class theClass and initialise the instance variables to 5, 10.75 and the string Class. e) Write a definition (heading) for a copy constructor for the class.arrow_forward
