it is impossible to do that with Scanner, however you can use the swing class'  [url=http://java.sun.com/docs/books/tutorial/uiswing/components/passwordfield.html]JPasswordField

Generally, you can't and don't do much manipulation with the command line shell. If you were making a professional program you would most likely be making an application, applet, or using third-party graphics where it would be easy to hide or replace input.

There is also an external API called JNI which gives you more control over the command line shell, but I have never used it.
