I want to take any input in Java without pressing the enter key. Actually I want to make a password input program, so that as soon as the user enter any character, I can clear the screen and replace the characters with an equal number of asterisks ("*"), like the typical password entries made anywhere in the web. Most importantly, I would like to do the same in the Java Terminal Window, not by using those applet methods. Please tell me if i would have to supply more details. I am using BlueJ.

Thank you, Mayank.

  • Not possible without going native. See http://stackoverflow.com/questions/1864076/equivalent-function-to-cs-getch-in-java as well. – Usman Saleem Oct 17 '11 at 14:50

You may want to have a look at the Console's readPassword(...) methods (needs Java 6+).

Or, when using Java 5 (or less), have a look at this article: Password Masking in the Java Programming Language, especially the paragraph Command-Line Input Masking.
