Exercise $4\mathrm{.}57$ Implement the findProduct method. This should look through

the collection for a product whose id field matches the ID argument of this

method. If a matching product is found, it should be returned as the method's

result. If no matching product is found, return nu $11.$

This differs from the printProductDetai$1$s method, in that it will not

necessarily have to examine every product in the collection before a match is

found. For instance, if the first product in the collection matches the product ID$,$

iteration can finish and that first Product object can be returned. On the other

hand, it is possible that there might be no match in the collection. In that case,

the whole collection will be examined without finding a product to return. In

this case, the nut$1$ value should be returned.

When looking for a match, you will need to call the get ID method on a Product.
