Can Java detect keyboard escape codes?

pdibona · 10-11-2002, 07:52 AM

I am writing a specialized shell in java (no Swing or AWT). This is an application that will run in text-only mode with the user typing commands.

How can Java detect if the user hit the "up arrow" or "down arrow"?
I tried using the read() method of InputStream to get one byte from the
stream, but it blocks until the user hits a carriage return.

Any ideas?

I'm assuming inputsteam is the class that reads things...i use 2 different classes called easy reader and easywriter(not written by me). There are no methods in my class to do what you are trying to do. Uou should look on sun.com website and look at all the method or try to a class somebody wrote to handle that. It def. sounds possible. Remember to read the documentation...sorry im not much help
