Java Inventory Program 1-3

Instructions: This document contains the tutorials for Inventory programs 1-3. These programs will be separated by pages between each program in addition to being color coded. NOTE: This information will need to be copy and pasted into a notepad document. For your own benefit, please do not plagiarize this work. // Inventory program part 1 Inventory1. java // // A product class that stores and makes the name of the product, the item number, the number of units in stock, and the price of each unit retrievable. // Java app. that displays the product name, the item number, price of each unit, and the value of inventory. mport java. util.
