Error that i should know how to fix.

[dorno83]

Ok Im getting this dumb error and I think I have to initialize something just not quite sure how.
Or maybe Im writing it wrong

the error im getting is "variable tempStation might not have been initialized"

I have the location of the error marked with a smiley face.
Any help would be greatly appreciated.
thanks

Anyone????

Can you copy-paste the full error message here to see.

[dbashby]

As someone who is just learning I may well be on the wrong track but there is no tempStation in your declaration of variables that you have commented near the top of your code (instance variables)????

Maybe?

Different people have different styles. But better to follow the commons as well. ;)

You are declaring a new tempStation, using the value of itself. The value of tempStation.getStationNumber() will need to come from somewhere else.
