HR email handler

The HREmailHandler class extends the MainEmailHandler class. It assigns the keywords specific to the HR email handler and contains the processEmailFinal() method:

public class HREmailHandler extends MainEmailHandler {

    protected String[] assignedKeyWords() {
        // setup keywords for the receiver team
        return new String[]{"career", "job", "faculty"};
    }

    @Override
    protected String[] keyWords() {
        return new String[0];
    }

    protected void processEmailFinal(String emailText) {
        System.out.println("The Human Resources Team processed the email.");
    }

    @Override
    public void setNextEmailHandler(UniversityEmailHandler emailHandler) {

    }
}

The processEmailFinal() method just shown informs the user that the HR email handler took care of the received email.
