You're confusing the compiler with that cast. Remove it and the error will go away.

Try this.
List<Number> numbers = new ArrayList<Number>();

Since Java version 7, you no longer have to say <Number> the second time. Instead, you can use the "diamond" operator <> and save some typing. The problem here is the cast.

I wonder why the author did the casting orignially in the document i read. Is there is aplace or necessity of casting ArrayList to List at all?
please advise

I can't think of a situation where that cast makes sense; it may just be a typo.
