Exit Collection.forEach() by condition?

Question

Java

Good afternoon.
I understand that a lot of time has passed since the advent of Java 8, but nevertheless, the scenario for using Collection.forEach() is the same everywhere - we go through all the elements of the collection and do something with each element.
And if I need to implement another fairly typical scenario. The goal is to go exactly until I find something in the collection:

for (Item item : items) {
            if (item  ... pass some condition ...) {
                found = true;
                break;
            }
}

Is it possible to do this in Java 8 style?
More often in such loops, I would like to exit the method:

for (Item item : items) {
            if (item  ... pass some condition ...) {
                return item.getSomeValue();
            }
}

Is this possible in Java 8 style?

If you need this, then you misunderstand the nature of the streaming API. forEach()is not a cycle in its usual imperative sense. The correct solution is to pre-filter the stream so that forEach()only the necessary values ​​​​are received. Or the right one. If you really need it, then you can get an iterator from the stream and bypass it in the classic while(iterator.hasNext()).
