hi danpost how are you. I am doing this hospital program that involves doing a GUI. it has lot of inheritance, composition, encapsulation and abstraction in it. I have covered all of that except the polymorphism part. The problem that i am having is in some of the class I keep getting this error: in the job class, it says constructor Exchange in the class Exchange cannot be given type. in the dermatologist class it says constructor Doctor in the class Doctor cannot be given type. in the cardiologist class it says constructor Doctor in the class Doctor cannot be given type. here is the codes
?

super(firstName,lastName,dob);
try to call a constructor in their super class Doctor with the parameters (String, String, Date_of_Birth). However, there is not such a constructor in the Doctor class. There is only the (String, String, Date_of_Birth, String, String, Job, String) constructor so you are getting this error. You could add this:

public Doctor(String firstName, String lastName, Date_of_Birth dob)
{
    super(firstName,lastName,dob);
}
