When overriding a non-virtual method in Java, use of the @Override annotation is recommended, but what if I implement an abstract method? Should I use @Ov
Yes - again, it tells the compiler, "I really want to be overriding a method here. If there isn't a corresponding method to override, I've made a mistake and want to be told about it!"
Personally I think it's a pity that this is just an annotation rather than part of the language (as it is in C#) but that's the benefit of hindsight, of course.
