How do i add the matched element from one array into another array

String searchCriteria = request.getSearchCriteria();

Product product1 = new Product();
            Product product2 = new Product();
ArrayList<Product> products = new ArrayList<Product>();
            products.add(product1);
            products.add(product2);
            for (int i=0; i<=products.size(); i++){
                  if (products.contains(searchCriteria)){
                        ArrayList<Product> SelectProducts = new ArrayList<SDProduct>();
                        ----- I'm trying to add the products.contains(searchCriteria) into selectProducts--------------
                  }
                  }
            }
            SearchProductResult res = new SearchProductResult(SelectProducts, searchCriteria, showResult);
            return res;
