To close standard libs gap, let's assume I have static functions for odd() and take() as well as Java8 stream APIs statically imported. After this, it looks pretty compact and readable: take(10, i -> range(0, i)
.mapToObj(j -> odd(i))
.collect(joining(" ")))
.collect(joining(" "));
For reference, odd and take will look like this: private static String odd(int i) {
return Boolean.toString(i % 2 != 0);
}
private static <T> Stream<T> take(int n, Function<Integer, T> f) {
return Stream.iterate(1, i -> ++i).map(f).limit(n);
}
