Finance email handler

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

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

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