Question

pls help me with it.

you just need to answer the question in Appointment.Java, There is only 1 question u need to answer!

Appointment.Java

package option1.stage3;

import option1.stage1.Doctor;

import option1.stage1.Patient;

import option1.stage2.TimeSlot;

public class Appointment {

private Doctor doctor;

private Patient patient;

private TimeSlot timeSlot;

public Doctor getDoctor() {

return doctor;

}

public void setDoctor(Doctor doctor) {

this.doctor = doctor;

}

public Patient getPatient() {

return patient;

}

public void setPatient(Patient patient) {

this.patient = patient;

}

public TimeSlot getTimeSlot() {

return timeSlot;

}

public void setTimeSlot(TimeSlot timeSlot) {

this.timeSlot = timeSlot;

}

public Appointment(Doctor doctor, Patient patient, TimeSlot timeSlot) {

setDoctor(doctor);

setPatient(patient);

setTimeSlot(timeSlot);

}

public Appointment(Patient patient, TimeSlot timeSlot) {

setDoctor(null);

setPatient(patient);

setTimeSlot(timeSlot);

}

public String toString() {

if(doctor != null)

return patient+" with "+doctor+" for "+timeSlot;

else

return patient+" for "+timeSlot;

}

/**

*

* @param other

* @return true if calling object conflicts with parameter Appointment.

* we say two appointments conflict if they are with the same doctor

* and the timeSlots overlap.

* HINT: Use method equals from Doctor class and method overlapsWith from TimeSlot class

*/

public boolean conflictsWith(Appointment other) {

return false; //TO BE COMPLETED

}

}

This is the test file to test if the codes are working.

Let me know if any codes above are no working！

thank you so much！

Answer 1

Here is the completed code for Appointment.java. There was only a couple of lines of code to be added. Let me know if you have any doubts. If you are satisfied with the solution, please rate the answer. Thanks

Other classes are not attached, as there was no change in any of them.
