We can use our new repository to restrict the results retrieved from complex data. We can combine a call to the getAll method with stream, filter, and collect to generate a Stream<MobileGame>, apply a filter with a lambda expression as an argument, and call the collect method with Collectors.toList() as an argument to generate a filtered List<MobileGame> from the filtered Stream<MobileGame>. The filter method receives a Predicate<MobileGame> as an argument that we generate with a lambda expression and we apply the filter to the Stream<MobileGame>. The filter method returns the stream of the elements of the input stream that matches the specified predicate. The method returns a stream with all the elements for whom the Predicate<MobileGame> evaluates to true.
