How to Grab Key Events Outside Java

Instructions

1

Open the Java editor that you use to write your code and load up the project you want to edit. Double-click on your Java source code file.

2

Add the event handler that detects when a user presses a key. The following Java code detects each key press:

public boolean mouseDown( Event evt, int x, int y)


The Java code that you want to execute when the key is pressed is placed within the brackets.

3

Add code to the event handler. The following example echoes the keystroke back to the user:

System.out.println("You pressed the " + evt.key + " key.");
