This is a dupe of the very same set of questions posted under a different topic yesterday.
Nadeem, please do not repeat post.
And as Eric points out in this topic, and I pointed out in the other, JavaRanch is not the place to come to get your homework done for you. You will find much help here, but you must make the effort to do your own work.
I am closing this topic. Please continue any discussion
here.
