Code sample

===========================
import java.util.PrimitiveIterator;
import java.util.stream.IntStream;

public class Test {
    public static void main(String... args) {
        PrimitiveIterator.OfInt iterator = IntStream.range(1, 5).iterator();
        try { iterator.forEachRemaining(
                (int i) -> { if (i < 3) System.err.println(i); else throw new RuntimeException("Stop!"); });
        } catch (Exception e) {
            System.err.println(e);
        }
        System.out.println("iterator.nextInt() = " + iterator.nextInt());
    }
}
