I don't think it is possible to query the capslock/numlock state directly in JavaFX 8. Robert's solution uses the AWT Toolkit, which is not JavaFX, but should work for you. You might want to create a feature request in the JavaFX issue tracker for locking key state tracking.

You will want this import:

import java.awt.Toolkit;

If you are wanting it on no matter what, just turn it on with:

Toolkit.getDefaultToolkit().setLockingKeyState(KeyEvent.VK_CAPS_LOCK, true);

If you want to check first if it is off, then turn it on:

if (!Toolkit.getDefaultToolkit().getLockingKeyState(KeyEvent.VK_CAPS_LOCK)) {
        Toolkit.getDefaultToolkit().setLockingKeyState(KeyEvent.VK_CAPS_LOCK, true);
    }

Lastly, if you want to toggle between the two states:

if (Toolkit.getDefaultToolkit().getLockingKeyState(KeyEvent.VK_CAPS_LOCK)) {
        Toolkit.getDefaultToolkit().setLockingKeyState(KeyEvent.VK_CAPS_LOCK, false);
    } else {
        Toolkit.getDefaultToolkit().setLockingKeyState(KeyEvent.VK_CAPS_LOCK, true);
    }
