What is Stream.. Input or Output what is the difference

[pjerald]

Forgive me for this silly one. But for me it is essential.

Is an inputStream is a tool for reading the data.. or inputStream is a thing that contains the data to read ?

It's an object from which you can read bytes; that's all you need to know. Sources
such as files or sockets or strings or whatever can give you an InputStream so
that you can read bytes from those sources.

I just try to understand these things.. correct me..

OutputStream is an object to which we can write bytes; and Sinks such as files or sockets or strings or whatever can give us an outputStream so that we can write to those sinks.

Yep, correct; although I'd change 'String' to byte arrays (both for input and output;
my bad; sorry. Strings are about characters, Streams are about bytes).
