How can I get the Caps Lock state, and set it to on, if it isn't already?
You can use getLockingKeyState
to check if Caps Lock is currently set:
boolean isOn = Toolkit.getDefaultToolkit().getLockingKeyState(KeyEvent.VK_CAPS_LOCK);
However, it's unnecessary -- setLockingKeyState
doesn't toggle the state of the key, it sets it. If you pass it true
it will set the key state to on regardless of the original state:
Toolkit.getDefaultToolkit().setLockingKeyState(KeyEvent.VK_CAPS_LOCK, true);
