Create a public class Product. Each product stores a single String name set by the constructor. $($Reject null names using assert.$)$ Provide only a getter for the name following our usual naming conventions.

Also store a rating value as an int. Initialize it to $0$ in the constructor and provide a setter and getter for it$.$ Your setter should only accept values between $1$ and $5,$ inclusive. Enforce this using assert.

Product should also provide a single class method named betterProduct, which accepts two non$-$null Products and returns whichever has the better rating. If both ratings are the same, return the first Product.
