When do you use Java’s @Override annotation and why?

I see a lot of @override element in many codes and I don't exactly know what it means. for example:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

I don't know what it means and I don't understand what am I overriding. Can someone please help me?

Answer 1

It means you are overriding a method of your parent class (the one you extend from).
