Reading just one character from stdin

Learning some Java. I'm making a sort of brainfuck compiler out of boredom
http://en.wikipedia.org/wiki/Brainfuck
It's all done except the part where I have to read a byte from the standard input (works fine with bf programs that don't require input, even a cool ascii fractal generator i found).

So my question is, how can i read a single key from the keyboard? I could use a Scanner and make it read from System.in and take the first character, but the user would have to type something, which would appear on the screen, and then press enter, and that's not what I want.
I just want to read one character from the keyboard, without it appearing on the screen, and without the user having to press enter after it.

Any help?

Fuck off

I cant find `eval` and `read` functions in Java :-(

cbreak()

#include <termios.h>

        struct termios io;
        tcgetattr(0, &io);
        io.c_lflag &= ~ICANON;
        tcsetattr(0, TCSANOW, &io);

You guys are fucking useless

DURR HOW DO I UNDERSTAND HOW TERMINALS AND THEIR EMULATORS WORK

Just press Ctrl-d after you've entered the character you want instead of enter.

So how come the temperature conversion program thread with the most basic question in the world does get serious replies?

Because you're a moron?

Your question has been answered here and was answered several times in the thread you made at /g/, coupled with the fact that you could just easily Google this and get a simple answer makes people not want to respond to your thread.

>>10
How do you know there is a thread on /g/. Do you actually go there?

>>11
Yes. I also love importing memes from /b/ and /g/ to the delight of the denizens faggots of /prague/. lulz

>>11

Yeah, I do.

I just went to /g/. They discussed the bad ISP choices of their parents.

>>10
almost. It's because nobody who posted here knows the answer, except >>7 , or they wouldn't be saying it can be answered by a simple google search. but their ego is too weak to admit it.
If I come here and ask the absolute dumbest question in the world, I get a serious reply, but if I ask something nobody knows I get replies of the manner "your question is too dumb to deserve an answer"

System.in is (almost?) always going to be line-buffered when fed from a shell. There's no way around it short of messing with system-specific stuff. If you want unbuffered input then write a simple GUI and use a key listener.

>>15
The question has already been answered twice, you're just too dumb to understand it.  Go away.

>>17
I see only one half-answer.

>>18
You're not looking well enough.

>>19
Your gay.

>>20
What about my gay?

>>21
Yo'ure it is what.
