Create a Java application that displays the product number, the name of the product, the
number of units in stock, the price of each unit, and the value of the inventory (the
number of units in stock multiplied by the price of each unit). Pay attention to the good
programming practices in the text to ensure your source code is readable and well

I'm having trouble with the code to print the value of the inventory. Please assist.

So, someone did your work (or most of it) for you, but left you with a little nugget to complete yourself, and so now, you'll post here (without even removing the comments that clearly spell out that someone else did it) hoping that we do even that litlle nugget for you?

What a maroon! (Spelling intended.)

Do Your Own Homework! This is not a homework service. Normally I would have been more than happy to help point out what was wrong (not do it for you, though), but looking at that code, which so clearly spells out that you didn't do it, and that you're then posting it here, in that form, clearly spells out that you didn't even attempt to finish it, just disgusts me.

commented: Agreed +2

for what? For expecting us to help you cheat or for being stupid enough to make your attempts easy to detect?
