1. Extend the programme in Part 1 (3) so that it has two constructors [Employee(String firstName, String sureName) and Employee(String firstName, String sureName, int empAge). 2. Refactor the code in (1) so that sub-classes PermenatEmployee and TepmporaryEmployee will be derived from the super-class Employee. The PermenatEmployee TepmporaryEmployee will have the attribute hourlyWage, so the salary attribute is no longer an attribute of Employee. Override the calculateSalary() method in TemporaryEmployee class so that the salary is calculated as hourlyWage numberOfHours. will have the attribute monthlySalary whereas 3. Use StarUML application to draw the class diagram for the code in part 2.

3. Write a console programme that will create a list of Employees (using LinkList).
Employee class will have firstName, sureName,age, dOb, salary, contact and address
as attributes. The Employee class MUST implement all Mutator or Setter methods and
Accessor or Getter methods (i.e. setFirstName(), getFirstName())and calculateSalary()
method. Show that you can add emp1, emp2, emp3 to the LinkedList.
