I need to override the toString() method with my own, however I am not sure how to reference back to the parameters for the constructor of the class. I've included my code below. I even tried giving the class instance variables of the same name, however the error said the code was "unreachable." What am I doing wrong? /** * Superclass for the different types of appointments. * TODO: Appointments have a description & date MM/DD/YYYY * TODO: method: occursOn(int year, int month, int day); * 4 method constructor: year, month, day, description */ public class Appointment { /** * the constructor method for an Appointment. * * @param year - the year of the appointment. * @param month - the month of the appointment. * @param date - the day of the appointment. * @param description - a short description of the appointment. */ publicAppointment(intyear, intmonth, intdate, Stringdescription){ } /** * Method to return a string representation of the appointment. * Will be inherited by the subclasses. * @return - a string representation of the appointment object. */ publicStringtoString(){ returnthis.description +" on "+this.month +"/"+this.day +"/"+this.year +". "; } }
