Modify the program to have a command to delete a reservation.

Modify the program to define and use a method public void makeSeatReservations(Scanner scnr) so that the program's main() is cleaner. The makeSeatReservations() method should have a Scanner object passed to it to read the user's input.

import java. util. ArrayList;
import java. util. Scanner;

public class SeatReservation {

// Arraylist for seat reservations
private ArrayList allSeats;

public SeatReservation() {
allSeats = new ArrayList();
}

public void makeSeatsEmpty() {
int i;
for (i = 0; i < allSeats. size(); ++i) {
allSeats. get(i).makeEmpty();
}
}

public void printSeats() {
int i;
for (i = 0; i < allSeats. size(); ++i) {
System. out. print(i + ": ");
allSeats. get(i).print();
}
}

public void addSeats(int numSeats) {
int i;
for (i = 0; i < numSeats; ++i) {
allSeats. add(new Seat());
}
}

public Seat getSeat(int seatNum) {
return allSeats. get(seatNum);
}
