Nice Solution, I would have to look at the other methods added with Java 11.

there is no value for '' in your dict1

Why do the full tests when submitting the Java version call a method called Line.Tickets() instead of Line.tickets() (upper case T instead of lower)??!?

Again, the tests are ok, think about how you give change when they pay you with a 100 dollars bill (there are two ways, you're using the wrong one when you can use the other).

No only two this examples are wrong remaining all are correct check and get back to me

Both tests are ok, you're giving back the change wrong.

NO NEED TO SCREAM LIKE THAT!...

it's in your code, debug it by reading the full error message: it even tells you where the problem is and what it is.

edit: oh, wait, seems I'm not awake enough. Lemme take a look.
edit²: ok, I'm effectively not awake enough, but it is in your code.

EVERY THING IS PREFECT EXCEPT THIS ERROR
