InputStream.read should throw an EOFException instead of returning

It may bee goofy but it is very likely to be a whole lot faster.
Throwing and catching an exception is probably going to be a lot
slower than checking the return value.

Besides, there's nothing exceptional about reaching the end of a
stream. One would venture to say that one nearly always reaches the
end of a stream, *unless* something exceptional happens.

Right; the most Java-ish thing would be for Streams to be
iterator-like:

   while (stream.hasNext())
   {
       char c = stream.next();
   }

or even

   for (char c: stream)
   {
   }

Is this a good time to mention that in python, iterators don't have a
hasNext method, and instead their next method just throws StopIteration
at the end? :)

It is obviously interesting for the question being debated.

But Python is a different language from Java.
