You have asked these questions in a Javascript forum, ( Javascript != Java )
which is thought to be a kind of HELP desk for
people trying to acquire programmer skills
using the courses.

I would suggest you use a google search
== the Book ==
java [your question]

== for discussions / opinions ==

Please don't put your homework questions on here.
Do your own homework, not take others.
That's considered plagiarism.
