Hide input on command line

Question

I know that command line interfaces like Git and others are able to hide input from a user (useful for passwords). Is there a way to programmtically do this in Java? I\'m ta

Answer 1

There is :

Console cons;
char[] passwd;
if ((cons = System.console()) != null &&
    (passwd = cons.readPassword("[%s]", "Password:")) != null) {
    ...
    java.util.Arrays.fill(passwd, ' ');
}

but I don't think this works with an IDE like Eclipse because the program is run as a background process rather than a top level process with a console window.

Another approach is to use the JPasswordField in swing with the accompanying actionPerformed method:

public void actionPerformed(ActionEvent e) {
    ...
    char [] p = pwdField.getPassword();
}
