Did you mean "asterisk"? – Hot Licks Mar 22 '13 at 17:01

You can use JPasswordField to do that; Below is an example:

    private JPasswordField password;
    private String typedPassword;
    private final String defaultPassword = "yourDesiredPassword";

    public void createPasswordField(){

    password = new JPasswordField(30);
    password.setBounds(280, 240, 90, 20);
    password.setEchoChar('*');
    password.setBackground(Color.white);
    password.addActionListener(new ActionListener() {

        @Override
        public void actionPerformed(ActionEvent e) {

            password = (JPasswordField) e.getSource();
            char [] tempPass = password.getPassword();
            typedPassword = new String(tempPass);

            if (!typedPassword.equals(defaultPassword)){

                JOptionPane.showMessageDialog(null,
            "Your password is not correct",
            "Stack Over Flow example",
            JOptionPane.ERROR_MESSAGE);
            }
        }
    });
}

can you please give example with my code? or change my for code it? – Sojib Mar 22 '13 at 17:23
Sure, just give me a couple of minutes. – Survivor Mar 22 '13 at 17:29
@Sojib, Why don't you read the JPasswordField API where you will find a link on `How to Use Text Fields`, which will contain working examples on this as well as other Swing components. Don't expect people to spoon feed you answers. Do some reading and learning on your own. – camickr Mar 22 '13 at 18:03
@Sojib, I'm sorry but what you want is not suitable for Java; I mean you can do that in C much easier and in Java you can do this kind of program much easier by creating a GUI ( Graphical User Interface ); make a JFrame and JPanel and on to that JPanel add a JPasswordField and you can use what I posted above for the JPasswordField. If you still wanna do this in your way, take a look here: http://stackoverflow.com/questions/10819469/hide-input-on-command-line – Survivor Mar 22 '13 at 18:42
