I can open a console input prompt to the user by using:

BufferedReader bufferRead = new BufferedReader(new InputStreamReader(System.in));
String s = bufferRead.readLine();

Is there anyway to auto complete a user's input when they press tab? For example, they type:

>>: eat app[press tab]
>>: eat apple

Because apple is a known word in my code. Is there a way to do this without using libraries like JLine or JavaReadline

I wouldn't user a `BufferedReader`, it won't capture the individual key strokes.. – MadProgrammer Aug 29 '13 at 04:26
I can't see any way to intercept the keystrokes from stdin. You will need something that is much more lower level. – MadProgrammer Aug 29 '13 at 04:32
