Key event: The actions that are performed using a keyboard when a key is pressed released or typed will in turn fire an event on the node or scene is called as key event. The actions or events are captured using the “KeyEvent” object. The events that are associated with the mouse event object gather location based on “getcode()” method of the key event. Registering the handle object: To register the handle object, it is necessary to invoke the registration method of the source object. To register an handle the “setOnAction(handler)” gets invoked by the source object.
