Converting Java Code to a UML diagram

I have to convert the following Java code to a UML diagram, however I'm not sure whether I have done the associations between the classes correctly. Please you advise me whether or not the UML diagram is correct. 

public class Booking {

    private String name;

    private Time time;

    private Table[] tables;

    public Booking ( String n, int st, int en, int num ){
    }

    public int getStart (  ){
        return 1;
    }

    public int getEnd (  ){
        return 1;
    }

    public Table[] getTables (  ){
        return new Table[3];
    }

    public int getBookingSize (  ){
        return 1;
    }
}

public class Time {

    private int startHour;

    private int endHour;

    public Time ( int st, int en ){
    }

    public int getStart (  ){
        return 1;
    }

    public int getEnd (  ){
        return 1;
    }
}

public class Table {

    private int number;

    private int seats;

    public Table ( int num, int sz ){
    }

    public int getNumber (  ){
        return 1;
    }

    public int getSeats (  ){
        return 1;
    }
}

public class Restaurant {

    private Booking[] bookings;

    public void makeBooking ( String n, int st, int en, int s ){
    }


    public void cancelBooking ( String n ){
    }

    public Table[] getTables ( String n ){
        return new Table[2];
    }

    public int getStTime (String n) {
        return 1;
    }

    public int getEndTime (String n) {
        return 1;
    }
}

I will ignore methods and attributes, because they are trivial and not interesting (and getters should ideally be omitted).

enter image description here

There are several differences to your diagram:

  • Restaurant may not have any bookings at all, so it should be *, and not 1..*
  • Booking needs only one Time, because Time already contains the start and end
  • I don't know why Restaurant has start and end time. I will assume it's to show opening hours (which is a single instance of a Time.
  • According to your code you can have Booking on more than one Table. In your diagram only one was possible.
  • One Table may have many Bookings. In your diagram it could have only one. (Of course there is run-time constraint that two Bookings shouldn't book the same Table within the same Time period, but that should be expressed in OCL or as a note)
  • Added role names to the association endpoints (period,openingHours,...)

More notes:

  • Time should either contain a single time, or it should be renamed to Period or TimeInterval. The current naming is confusing.
  • Multiplicity on the other side of relations from Time can be omitted (since they do not have much meaning here).
