class employee {
private String ID;
private String Name;
private director Director;

public void setDirector(director,Employee_Director){
Director=Employee_Director;
}
}

class director extends employee {
public void fire(String Employee_ID){

}
public void assign_job(String Employee_ID){

}
}

public class Main
{
public static void main(String[] args) {

employee A = new employee();
A.setID("e87090013");
A.setName("Tom Ho");

director B = new director();
B.setID("c80010026");
B.setName("Jay Cho");
}
}

employee.setDirector的方法，出現錯誤 error <identifier> expected

請問要如何解？謝謝 ^_^
