Java KeyListener is an interface used to handle keyboard events in Java applications. It defines three methods: Java keyPressed(), Java keyReleased(), and Java keyTyped(), which are invoked when a user interacts with the keyboard. Java KeyListener is typically implemented in GUI applications built with Java Swing or AWT for capturing and responding to user keystrokes. Introduced in Java 1995 with Java 1.0, KeyListener is used in interactive applications, such as games or text editors, to handle keyboard input.
