> An overridden method from an interface or abstract class must be marked with {{@Override}} annotation. To accurately determine whether the overriding is successful, an {{@Override}} annotation is necessary. Meanwhile, once the method signature in the abstract class is changed, the implementation class will report a compile-time error immediately.
