Academic email handler

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

public class AcademicEmailHandler extends MainEmailHandler {    protected String[] keyWords() {        // setup keywords for the receiver team        return new String[] {"academic"};    }    protected void processEmailFinal(String emailText) {        System.out.println("The Academic Team processed the email.");    }    @Override    public void setNextEmailHandler(UniversityEmailHandler emailHandler) {    }}

The processEmailFinal() method of the AcademicEmailHandler class shown informs the user that the academic email handler took care of the received email.
