I am writing a java project about find station using name

the code can pass the test about itself but it can't pass the main test.and always have the exception I don't know why.

• TrainStation leftTerminus : the terminal station on the left

• TrainStation rightTerminus : the terminal station on the right

• get name means get the name of the station

• get tight means get the right staiton

• thank you!
