Does Java 8 provide a good way to repeat a value or function?

by

For this specific example, you could do:

IntStream.rangeClosed(1, 8)
         .forEach(System.out::println);

If you need a step different from 1, you can use a mapping function, for example, for a step of 2:

IntStream.rangeClosed(1, 8)
         .map(i -> 2 * i - 1)
         .forEach(System.out::println);

Or build a custom iteration and limit the size of the iteration:

IntStream.iterate(1, i -> i + 2)
         .limit(8)
         .forEach(System.out::println);
