    I don't think this is possible without JNI (native code). Java console IO is simple and line oriented, it doen't provide full terminal access. – markspace Sep 09 '18 at 07:51
  • This type of reading from console called raw. You can do this character by character. here is one solution https://stackoverflow.com/questions/1066318/how-to-read-a-single-char-from-the-console-in-java-as-the-user-types-it – M. Doosti Lakhani Sep 09 '18 at 08:16
  • I recommend you to look for a solution that match with your system. Like Windows or Mac. Because this type of things is an OS shell dependent. – M. Doosti Lakhani Sep 09 '18 at 08:19
