197. Extending Stream with containsAll() and containsAny()

Let’s assume that we have the following code:

List<Car> cars = Arrays.asList(
  new Car("Dacia", "diesel", 100),
  new Car("Lexus", "gasoline", 300), 
  ...
  new Car("Ford", "electric", 200)
);
       
Car car1 = new Car("Lexus", "diesel", 300);
Car car2 = new Car("Ford", "electric", 80);
Car car3 = new Car("Chevrolet", "electric", 150);
List<Car> cars123 = List.of(car1, car2, car3);

Next, in the context of a stream pipeline, we want to check if cars contains all/any of car1, car2, car3, or cars123.

The Stream API comes with a rich set of intermediate and final operations, but it doesn’t have a built-in containsAll()/containsAny(). So, it is our mission to provide the following final operations:

boolean contains(T item);
boolean containsAll(T... items);
boolean...
