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.

Person and Customer Classes
Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. 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. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
employee and production worker 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, then use the object’s accessor methods to retrieve it and display it on the screen. satak overfallow

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.

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.

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_forward
