How do I do an item that generates random loot?

Hello, I am currently in difficulty because I am currently in the process of creating a mod, except that I do not know anything about java programming. I would like to create an item allowing to have random loots. That is to say, that when I right click with the object, there is a  interface that appears, and it gives me random loots, and then the object is destroyed. And also make sure that such and such an item has such a percentage chance of appearing. Here is thank you for answering me quickly!
