How to convert Scala `for..yield` (for comprehension) to Java?

How to convert the following scala to java code?

for {
  x <- List(1, 2)
  y <- List(3, 4)
} yield (x, y)

Is it possible? what is yield?

I guess it's possible to convert any scala code to java...

@Tim already explained what is for..yield.

The Java code to do the same would be:

// Java doesn't have tuples, create your own type
record Pair(int x, int y) {}

List<Pair> result = 
  List.of(1, 2)
      .stream()
      .flatMap(x -> List.of(3, 4)
                        .stream()
                        .map(y -> new Pair(x, y))
      )
      .toList();

IMHO this is a great example of the conciceness and exprenessiveness of Scala, especially when working with collections.
