4) I knew this, and I've now changed everything that had to be changed
regarding the files' closing, be it for input or output. However, I
was wondering... if you don't close a file opened for reading, what does it
actually change? The way UNIX deals with files fortunately never locks
a[n] (currently) opened file. I simply ask what kind of problems the
non-closing of an opened file for reading would cause.

(Consider here that I only speak about the UNIX case; I know that Java
is evidently platform independent; as a result, one might want to
depend only on the VM and not on the OS. I just want to be informed
about the kind of troubles it might cause, and how the non-closing is dealt.)
