I was watching the video on Thinking in Parallel by Stuart. So decided to solve it before seeing his response in the video. Will update the solution with time. for now

Arrays.asList(IntStream.range(0, abc.size()-1).
filter(index -> abc.get(index).equals("#") ).
map(index -> (index)).toArray()).
stream().forEach( index -> {for (int i = 0; i < index.length; i++) {
                    if(sublist.size()==0){
                        sublist.add(new ArrayList(abc.subList(0, index[i])));
                    }else{

                    sublist.add(new ArrayList(abc.subList(index[i]-1, index[i])));
                    }
                }
    sublist.add(new ArrayList(abc.subList(index[index.length-1]+1, abc.size())));
});
