Question

the coding language is java

The start of Polymorphism Assignment

Outcome:

• Student will demonstrate the ability to apply polymorphism in a Java program.

Program Specifications:

Design the following program:

A person has a name, and age.

An Employee is a person.

An Employee has a company and position.

A SoftwareEngineer is an employee and a person.

A SoftwareEngineer has a rank (Junior, Middle, and Senior)

A SoftwareEngineer either C programmer, Jave programmer or both.

A Manager is an Employee and a person.

A Manager has a specialty.

A Manager specialty is either CEO, Division, or Sales.

An Intern is an employee and a person.

An Intern has duty.

A Security is an employee and a person.

A Security has a position (to guard).

An administrator is an employee and a person.

An Administrator has a type HR, recruiter, Secretary, and Legal.

  

All Employee type objects have a method named doThis();

   SoftwareEngineer -> doThis() displays I program web application.

   Manager -> doThis() displays I mange sales.

   Intern -> doThis() displays I test application.

   administrator -> doThis() displays I do the payroll.

Security -> doThis() displays I guard the main entrance.

... in general, all employee have a doThis() method that displays something.

Main()

Create the classes Person, Employee, SoftwareEngineer

Create the classes Manager, Intern, Security, administrator

   Create the doThis() method in each class

In main create the follow reference variables:

    SoftwareEngineer Hank (create this reference variable)

    Manager Terry (create this reference variable)

    Intern Mario (create this reference variable)

    administrator Paula (create this reference variable)

Security Danilo (create this reference variable)

    administrator Barry (create this reference variable)

    SoftwareEngineer Peyton (create this reference variable)

    Security Wayne (create this reference variable)

    Manager Phil (create this reference variable)

SoftwareEngineer Carlos (create this reference variable)

And then...

  Call each Employee doThis method (one at a time) passing each player.

Call the toString methods for each Employee object.

You are to turn in a UML, and CODE.

Submission Requirements:

• Follow the rules from the prior assignments.

YOU MAY NOT EVER:

• Use global variables.
• Use the word goto.
• Use the break command outside a case statement.
