Closing Stream?

Hey,

I wonder if @craigdennis should close the InpuStreamReader after reading the line or It isn't necessary in this case?

regards

Great question! You are right, I really should be closing that stream.

Ideally that prompting would be in a class of itself and implement the AutoCloseable interface, then we could use the try-with-resources style. Or we could also create a reader in the try there and pass it as an argument to each method. Both solutions seem a little out of scope, but great idea spotting a bug!

The best idea is to probably add a finally clause to that try statement that closes the reader. The problem is if someone else calls the run method, the reader would be closed.

Thanks for pointing this out!
