Does 'extends Object' have a purpose or is it redundant?

Question

Following a tutorial on the internet regarding Soap development with Java, I found this link, with a rather unusual code for myself.

The code:

public         


        

Answer 1

Why not make it explicit?

I'm for adding it in - not everyone "implicitly" knows that every Java class implicitly extends Object. By writing it explicitly they don't have to guess.
