I have a couple of static methods, read from the console. In Maine, I launch both sequentially. Entered the data in one, closed the stream. The second method immediately falls out with an IOException .

Of course, you can put a BufferedReader in the class field and not close the stream, but I’m wondering if you can do without it.

    You can use the Console class to retrieve user data.

      Console cons; char[] passwd; if ((cons = System.console()) != null && (passwd = cons.readPassword("[%s]", "Password:")) != null) { ... java.util.Arrays.fill(passwd, ' '); }

    System.console() always returns the same object. cons.reader() will return the Reader you and you can close it - this will not affect its operation.
