Read DEL and BACK key from stdin

Is it possible to read DEL and BACKSPACE keys from standard in?

If I use:

System.in.read()

these keys are never returned.

Thanks.

the behavior of stdin from the OS point of view?

On your platform and most that we know, the OS buffers input on that stream
until it receives an end-of-line. That line is passed entire to Java to wrap
as an 'InputStream' input. It follows trivially that the Java stream cannot
see the characters you describe unless you escape them.

Have you escaped them?

"Never" is a very strong word.

I don't think you see anything until the user hits enter.

If you want to see things in a keystroke by keystroke way you need
some sort of gui TextField or the like where you can intercept the
event for each keystroke.

The other way to do it is to use C.
