Re: Key Logger vs Key Listener 13 Years Ago by harinath_2007 Keylogger is a software which will captures all your keystrokes and activity you do on the computer. Whereas KeyListener is a interface in java which you should implement in your java code if you want to capture key strokes. Making keylogger in java is NOT possible.

Re: Key Logger vs Key Listener 13 Years Ago by Akill10 There is no "Keylogger" interface in Java. So the thread title does not make sense. Anyway, to add to what harinath said, You cannot make a keylogger using java. It lacks the low level operating hooks needed to do it.
