Turning echo off in Java

[ctippur]

Hi all,

I would like to prompt the user for a password and turn off echoing
what the user inputs ("stty echo off" command in unix). Is this
possible in Java?
I really appreciate any input.

Thanks,
Shekar Tippur

Huh? This is a programming language, not an OS shell. It doesn't write
anything out unless you tell it to.

It does when reading characters on the command line.

It's entirely possible that the OP was looking for something non-command
line based, but didn't know how to ask for it in swing/awt/etc.

But in any case, I think that the solution you provided is both clever *and*
hysterical!

You gotta love the heroic leaps of effort that you can find here and there.

Puzzle: You are given a deck of cards all face down
except for 10 cards mixed in which are face up.
If you are in a pitch black room, how do you divide
the deck into two piles (may be uneven) that each
contain the same number of face-up cards?

The URL covers that too:

``If you wish to provide a graphical login dialog box for your
application, you can use the AWT's TextField class, which is a text
component that allows editing of a single line of text. To mask the
password field, use the setEchoChar method. For example, to set the
echo char to an asterisk, you would do the following:

TextField password = new TextField(8);
password.setEchoChar('*');''

There's also a Swing version.

But in any case, I think that the solution you provided is both clever *and*

It's a real problem for those writing command line tools in Java.

Echoing passwords to the screen is simply not normally acceptable.

It's good that there's a way around the problem - even if it is ridiculous.

Nothing is preventing you from running stty from within your application.

Only that it's not exactly portable...

No such claims were made, however I'm confident that it's portable
enough for the OP!
