How to toggle something using key releases

Question

I'm making an application using lwjgl and I'm having troubles with toggling using the same key. What I want is for the boolean to be toggled when I release the key. I have a method that returns the toggle state and checks for any changes at the same time, but this is proving kind of difficult and overly complex. Is there any way I can make this easier? If not, could someone tell me how to go about toggling with the same key?

Any help is appreciated, thanks in advance!

I figured it out myself, here's the code:

public class Input{
    private static boolean escDownOnLast;
    private static boolean escToggled;

    public static boolean isToggledOn(){
        if(Keyboard.isKeyDown(Keyboard.KEY_R)){
            escDownOnLast = true;
        }else if(!Keyboard.isKeyDown(Keyboard.KEY_R) && escDownOnLast && !escToggled){
            escDownOnLast = false;
            escToggled = true;
            return escToggled;
        }else if(!Keyboard.isKeyDown(Keyboard.KEY_R) && escDownOnLast && escToggled){
            escDownOnLast = false;
            escToggled = false;
            return escToggled;
        }
        return escToggled;
    }
}
