java - word (password) displays in asterisks - Console application

Question

I am trying to write a program which will allow two players to play "a guess word" game as part of my learning curve in Java. When prompted, player 1 types in a word but the screen displays an asterisk * for each letter in the word. Simply player 1 types a word but the word should be displayed in asterisks rather than characters. I seem to have problem getting this one right.

Is there any method(s) in Stream Buffer or Scanner class that'll allow me to do that above.

thank you.

Answer 1

The intuition that you should intercept input, save original data, and show it masked in the console. You can achieve that by separate thread working on it.
