how hide the input?

I am wring a console java application,get user`s keybord input by System.in
. I want to know how hide the user`s input ,etc.password?
thanks.

Try using the setEchoCharacter() method of class TextField
for example

TextField myText = new TextField(20);
myText.setEchoCharacter('*');

There's another method usable in subsequent versions of Java (beyond
1.02)...that's setEchoChar(char) --depending on which version you're
using.

Good luck

The console input comes with a readPassword() method, that should work to cover the users input. The info on it can be found here:

Hope this helps!
