Thread: cant solve this one out

im working on some project, and cant solve this Airport class I've been making, this class is working with two other classes written, Time1 and Flight, for some reason i can't figure this out, and it's not working at all...
kinda urgent ill be glad for help ASAP
ill be adding the other 2 classes as attachments.
this is the Airport class:

thanks for the reply,
1) its a comment because i got an error on posting the thread so tried a few things https://www.javaprogrammingforums.co...milies/eek.png
2)same for FullFli, it marked the word FULL for a forbidden word for some reason
3) whats incorrect with the flight constructor?

line 35 Flight class if doesn't have close brackets

fixed it, methods on AIRPORT still not working properly

what errors does it give to you?
