The example below show you how to activate the Num Lock button programmatically. Setting the locking state to Boolean.TRUE will turn the Num Lock on. package org.kodejava.awt; import java.awt.Toolkit; import java.awt.event.KeyEvent; public class TurnNumLockOn { public static void main(String[] args) { // Gets the default toolkit. Toolkit toolkit = Toolkit.getDefaultToolkit(); // Update the locking state […]
