Answer 1

Here is a one liner implementation using Java8 streams:

String input = "Thequickbrownfoxjumps";
final AtomicInteger atomicInteger = new AtomicInteger(0);
Collection result = input.chars()
                                    .mapToObj(c -> String.valueOf((char)c) )
                                    .collect(Collectors.groupingBy(c -> atomicInteger.getAndIncrement() / 4
                                                                ,Collectors.joining()))
                                    .values();

It gives the following output:

[Theq, uick, brow, nfox, jump, s]
