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

- Child Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. Core Class Components For the Vegetable 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 instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableJavaarrow_forwardParent 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_forward1.

Store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen. 2. ShiftSupervisor Class In a…arrow_forward
- Employee class Write a Python program employee.py that computes the cumulative salary of employees based on the length of their contract and their annual merit rate. Your program must include a class Employee with the following requirements: Class attributes: name: the name of the employee position: the position of the employee start_salary: the starting salary of the employee annual_rate: the annual merit rate on the salary contract_years: the number of years of salary Class method: get_cumulative_salary(): calculates and returns the cumulative salary of an employee based on the number of contract years. Round the cumulative salary to two digits after the decimal point. Example: If start_salary = 100000, annual_rate = 5% and contract_years = 3: Then the cumulative salary should be : 100000 + 105000 + 110250 = 315250 Outside of the class Employee, the program should have two functions: Function name Function description Function input(s) Function output(s) / return…arrow_forwardCruise Recreational Activities Example Recreational activities include things like aerobics, shuffle board, and swimming. Each activity is identified by an activity code and includes other information such as description. Classes are offered for each activity. A class is uniquely identified by a combination of the activity code and the day/time at which it is held. It is assumed that a specific class will never be offered for the same activity at the same day and time, although it could be offered on a different day and/or time. Other information about a class includes the enrollment limit and the current enrollment count. A class will never include more than one activity. A passenger can sign up for a class as long as there is sufficient room in the class. Passengers are identified by a unique passenger number. Other information stored about passengers includes name, address, and age. Passengers have no limit on the number and type of classes they can sign up for.

Example values are "Dog", "Cat", and "Bird". age: The age field holds the pet’s age. The Pet class should also have the following methods: setName: The setName method stores a value in the name setType: The setType method stores a value in the type setAge: The setAge method stores a value in the age getName: The getName method returns the value of the name getType: The getType method returns the value of the type getAge: The getAge method returns the value of the age Once you have designed the class, design a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet. This data should be stored in the object. Use the object’s accessor methods to retrieve the pet’s name, type, and age and display this data on the screen. *** I need help…arrow_forward

- NewspaperSubscriber class- create an abstract class named NewspaperSubscriber with attributes to contain the subscriber’s street address and the subscription rate. Include get and set methods for both these attributes. The set method for the rate is abstract. The setAddress method must prompt the user to enter the subscriber’s address through the use of a dialog box. Create a constructor for the base class. Create a toString() method that concaternates and returns the subscriber’s street address and rate for display. Create 3 child classes named SevenDaySubscriber, Weekday Subscriber, and Weekend Subscriber. Each child class has an additional attribute called subType, which is a String, that will store the type of newspaper subscription. Create a setType method that will set the type of subscriber as follows: “Seven Day”, “Weekday”, or“Weekend”. Create a setRate method for each child class that sets the rate as follows: a SevenDaysubscriber pays R18.00 per week for his newspapers, a…arrow_forwardThere are two types of data members in a class: static and non-static.
