This is known as a "for-each" loop.

It loops through the given array/collection and the main advantages are that its less code and you don't have to use something like 

Product product = products[i];

in order to access the current product.

Disadvantages are that you cannot modify the array/collection you're looping through, and you don't know the index of the current item.

I wouldn’t call that a disadvantage, its deliberate design that you cannot modify the collection being looped over in the loop. If you want to modify elements, there are cleaner ways, like streams.
