Examples of java.io.Console$ConsoleWriter

java.io.Console
Provider to read and write message to char-based console device. Any Console instance should be obtained via System.console(). If the standard input and output stream has been redirected, the System.console() will return null. @since 1.6

     * the {@link SubCommand} has been built, otherwise the {@link SubCommand#err} printer shall be used.
