Some suggestions to improve your code

1. Use constructor chaining in the Driver and Traveler classes:

   • In the Driver class, modify the constructor with parameters to call the superclass constructor using super(email, userName, password) instead of setting the fields directly.
   • In the Traveler class, modify the constructor with parameters to call the superclass constructor using super(email, userName, password) instead of setting the fields directly.

2. Remove unnecessary getters and setters:

   • In the Driver class, remove the getEmail(), setEmail(), and getUsername() methods since they are already inherited from the User class.

3. Use List interface instead of Vector:

   • In the Driver class, change the type of the rides field from Vector<Ride> to List<Ride>. Vector is a legacy class and is generally replaced by ArrayList or List in modern Java development.

4. Use @Override annotation consistently:

   • In the Driver class, add the @Override annotation to the equals() method to indicate that it is overriding the method from the superclass.

5. Simplify the doesRideExists() method:

   • In the Driver class, the doesRideExists() method can be simplified using a stream and anyMatch():

     public boolean doesRideExists(City from, City to, Date date) {
      return rides.stream().anyMatch(r -> Objects.equals(r.getFromLocation(), from) &&
                                          Objects.equals(r.getToLocation(), to) &&
                                          Objects.equals(r.getDate(), date));
     }

6. Override equals() and hashCode() methods in the Driver class:

   • In the Driver class, override the equals() and hashCode() methods based on the email field for proper object comparison and hashing.

7. Remove unused methods

   • I think that the removeRide in the Driver class is not used

8. Use the correct method names in the Message constructor:

   • It should be .getUsername instead of .getUserName
