• provide setter and getter methods of each member variable
• provide for a display() method that outputs the member variables

• Position class

• provide for 1 Employee(,,,,,) constructor
• provide setter and getter methods of each member variable
• provide the following methods:
• double compute Salary() that computes for the employees’ salary (refer to/analyze sample table in Payroll class below)
• void display() that outputs the member variables

• Payroll class
• In main() method:
• create 3 Departments

• create 3 Employees for each Position
• display the 18 Employees’ details in tabular form (Emp Num, Full Name, Position, Department, Status, Basic Salary, Rate Per Hour, Number of Hours Worked, Total Salary), e.g.:
• 12345 Melvin M. Ninal Dean CCS Active 10000.00 100 20 12000.00
