How to make the user input come up as dots in Java

Question

is there any way to display •••'s when a user is typing in the console? My program has a user entering a password for a MySQL database but I want it to show •••'s instead of their password when they type.

You have no direct control of the console, to the Java process it's just an input stream. If you want asterisks, you'll have to upgrade to a GUI interface. — Marko Topolnik, Sep 13 '16 at 16:54

You can use Console.readPassword() to disable echoing. I don't think there's any way to get a substitute character without JNI though.

Dont know about showing "." But instead you can use

char[] password = console.readPassword("Password? ");

to input password without echoing on screen.
