Your prof is mistaken.  It is completely possible to read binary images 
of number directly off the disk or wire without using string 
conversions.  I know he's simplifying, but it's the kind of 
simplification that causes confusion and misunderstanding later.  Plus 
he's wrong.

Programming I is "experience," it's fine to say where you're at now.

Oh, that's a bit different than what you stated.  I think we all assumed 
that your question was how to read a single 1000 digit integer (which I 
think is what you actually said).

For example:

   BigInteger bi =
     new BigInteger( "9872345804321275419287439182374123489894378" );

where that String is too large to be represented as a number by an int 
(or long, I think).
