Question

I need code for this in Java

We need a command line app that will be able to illustrate collecting data for inventory and showing purchases of that inventory. Start with a menu system that will allow the user to choose between functionality.

• Show a list of products (inventory)
• Add inventory (price, description, who is selling)
• Delete inventory
• Purchase a product for a user (removing it from inventory)
• Show a list of products sold including their purchaser
• Make sure to have dates on all activity

Type the UML diagram for the classes in the design portion. Feel free to add any other fields that you would like to share.

I don't understand the requirements u want the working app or the source code?
