1. Employee and ProductionWorker Classes
Write an Employee class that keeps data attributes for the following pieces of information:
• Employee name
• Employee number
Next, write a class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information:
• Shift number (an integer, such as 1, 2, or 3)
• Hourly pay rate The workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for each class.
Once you have written the classes, write a program that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object’s data attributes. Store the data in the object and then use the object’s accessor methods to retrieve it and display it on the…
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…

- Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…arrow_forwardParking Ticket SimulatorFor this assignment you will design a set of classes that work together to simulate apolice officer issuing a parking ticket.
