You mean you need to code a class 'Driver' that's a type of employee?
In that case you want to extend the employee class;
public class Driver extends Employee
public Driver() //constructor method
super.getData(); //calls the getData method in your Employee. Might not want to do this, this line's just here to show you how.
...etc, with additional methods/constructors to those in the Employee class.
Basically when you extend a class, your new class inherits all the methods and variables from your original class, but you can overload them by writing identically named methods in the subclass. So, say, Driver.compareTo() will call the same method as Employee.compareTo().
That should get you started. Since it looks like a homework I'm not gonna give you a fuller code example ;)
