Tehtävä

The factory produces products represented by Product objects, which have the fields id, weight, and quality.

  1. Filter the products to keep only those with a quality of "GOOD" and a weight greater than 10.0.
  2. Extract only the id of the filtered products using a method reference.
  3. Once the result is collected into a list, print the id of the selected products using a method reference to println.
