Question

THE BELOW IS IMPORTANT

Rewrite the above code so that

It has all of the correct access modifiers for good encapsulation.
Your code obeys the principle of encapsulation that obliges you to put each method in the proper class.
Your code uses NO getters and NO additional classes or methods. You are welcome to modify any existing methods (including signatures and bodies) and/or move them between the existing classes.
Your code DOES NOT modify any of the constructors.

Important notes:

You DO NOT have to write a main method.
You DO NOT have to write tests.
You DO NOT have to write Javadocs.
You DO NOT have to write interfaces to encapsulate data structures.
There should be no incorrect syntax or other compile-time errors.

The owner of a venue for events needs software to keep track of reservations. The venue can handle
two events in a day, one scheduled for the afternoon and another scheduled for the evening. Each
event consists of the type (wedding, bar mitzvah, etc.), the date of the event, and whether or not the
event will be held in the evening. A programmer writes the code given on the handout.
import java.util.LinkedList;
class Event {
// wedding, etc.
String type;
Date date;
boolean isEvening;
// true if the event is to be held in the evening
public Event(string type, Date date, boolean isEvening) {
this.type - type;
this.date = date;
this.isEvening = isEvening;
}
class Date {
string month;
int day;
int year;
public Date(string month, int day, int year) {
this.month = month;
this.day = day;
this.year = year;
class Reservations {
LinkedList<Event> events;
public Reservations() {
this.events = new LinkedList<Event>();
// adds the given event to the events list, as long as there is no
// date/time conflict with existing events in the list.
// returns true if the event was added, false otherwise
boolean bookEvent (Event newEvent) {
if (events.size() == 0) {
events.add(newEvent);
return true;
}
else {
// no other events, so no conflicts
for (Event e: this.events) {
if (hasconflict(newEvent, e))
return false;
/i conflict found, event not added
}
events.add(newEvent);
return true;
// no conflicts, so add event
// returns true if a conflict
boolean hasconflict (Event e1, Event e2){
return datesame(e1.date, e2.date) && e1.isEvening = e2.isEvening;
}
// returns true if both dates are the same
boolean datesame (Date di, Date d2) {
return d1.month.equals (d2. month) && d1.day == d2.day && d1.year == d2.year;
}
}
