/**
 * EXERCISE 2: Employee Class
 * PT821: Object-Oriented Programming - Classes and Objects
 *
 * TASK: Complete the Employee class for a company payroll system
 *
 * Requirements:
 * 1. Add the following private attributes:
 *    - employeeId (String)
 *    - fullName (String)
 *    - department (String)
 *    - basicSalary (double)
 *    - yearsOfService (int)
 *
 * 2. Create constructors:
 *    - Default constructor
 *    - Parameterized constructor (employeeId, fullName, department, basicSalary)
 *
 * 3. Add getters for all attributes
 *
 * 4. Add setters with validation:
 *    - basicSalary must be >= 500000 (minimum wage)
 *    - yearsOfService must be >= 0
 *
 * 5. Add behavior methods:
 *    - calculateBonus() - returns 10% of salary for each year of service (max 50%)
 *    - calculateNetSalary() - basicSalary + bonus - 15% tax
 *    - promote(String newDepartment, double salaryIncrease) - updates department and salary
 *    - displayPayslip() - shows detailed payslip
 *
 * 6. Test your class in the main method with at least 2 employees
