1. Define a class Appointment that has three instance variables: Id (int), slotld (int) and isAvailable (a boolean type; true if the appointment slot is available to book; false otherwise). Include appropriate constructors. Add display() method that returns a string containing appointment's information. Define another class Student that has three instance variables: studentld, Name and appointment information which is made by a student. Include appropriate constructors. Add display() method that returns a string containing student's information. Add an addAppointment (Appointment a) method which is invoked when a student wants to make an appointment. Inside this method there will be a condition that checks the availability of the appointment slot because there are only 10 slots for the appointment. Please note that, when an appointment is made, isAvailable field would be set to true. Write a Main class that includes a main () method for testing the functionalities of these two classes: Appointment and Student. Create an ArrayList of Student class for 11 students and invoke addAppointment(a) and display() methods of the Student and Appointment class appropriately. Remember that, for 1I student print a message "Slots are not available" because there are ten appointment slots.
