Masking password going wrong

[najihahnizar]

Hi,all. I have been deadlocked in finding solution for my codes.
I have been searching for three days, almost get what I want. Please review my codes below;

private String promptForText(String prompt, Character mask, DataInputStream in, PrintWriter out) throws Exception {
            String line;
            ConsoleReader consoleReader = new ConsoleReader(in, out);
            line = consoleReader.readLine(prompt, mask);
            return line;
        }

String pwd = promptForText("password:",'*',in,out);

The output I get:
password: f*a*c*t*o*r*y*

Thank You So Much.
