Answer 1

The @Override annotation is used to make your code easier to understand, because it makes it more obvious when methods are overridden.

Answer 2

@ starts an annotation. You can think of that as a machine readable commentary. There is only a limited number in the library, but in theory you can define your own.

Answer 3

Does it mean the @comments are seen in the output console?
