问题 I'm still learning about methods in Java and was wondering how exactly you might use an instance method. I was thinking about something like this: public void example(String random) { } However, I'm not sure if this is actually an instance method or some other type of method.

问题 Greetings, I have a game, and i want to save the objects ( creatues ) that move on canvas to a bundle so that when someone pauses/leaves the app, the objects can stay where they were.
