I think print and readLine cannot be compared.
Differences:
* print is always available. Both in -scripting mode as well as normal mode.
* readLine extension (as Jim pointed out) is available only in
-scripting mode. (scripting mode is meant "shell" style scripting with
nashorn)
* While it is usually okay/safe to use arbitrary output/print stream and
direct output there, read/readLine is expected read from console (meant
for interactive user input).
That said, it should be straightforward to define your own read/readLine
replacement function that uses ScriptContext's Reader.

That expanded my horizon, thank you.
However even though print() utilizes the given writer, E.G: Socket's
OutputWriter, readLine still uses the System.in even though I use
engine.getContext().setReader(InputStreamReader of a Socket). Would
that be some kind of bug? Because that makes Scriptcontext.setReader()
method kind of useless.

You have to be in scripting mode to to use those functions.

It's possible to add command line options when using from java.

This is exactly what I'm looking for. Is it possible to do this from
inside a Java application? I have tried readLine() and readFully()
methods before, but I'm guessing they are meant for the commandline
tool only.

That sort of thing?

Hello,
I apologize if this is not the place to ask, but I couldn't get a
satisfying answer from anywhere else so this is kind of my last
resort.
Is there any built-in function to get input from a user when using
NashornScriptEngine? print() method allows us to utilize both the
default OutputStreamWriter (System.out) and any writers that we set
using ScriptContext, but how can I make use of the reader which is
used by the engine?
Thank you,
Burak
