Hi Ron Jean, please go through the faq how to
UseCodeTags (<- link to click on). I have added them for you this time, and you see the code looks better instantly, doesn't it?
I see you named the method "displayFromExcel". But what actually it does? I'm afraid it does more than that, and that is the bad thing. Try to decompose your method into smaller methods, where each of them would do one and only one task, so your code could be readable by others.
