apparently you missed that we have a policy on screen names here at JavaRanch. Basically, it must consist of a first name and a last name, and not be obviously fictitious. Since yours does not conform with it, please take a moment to change it, which you can do right here.

"Lucky", JavaRanch is not a place where you can have other people do your homework. Please do your own homework, otherwise you will not learn anything.
