If I make changes to the ACTIVE_SKEW_LIST[0], will it also make the same changes to the Arraylist in the Map it is fetched from?

                if(SKEW_MAP.isEmpty() || !SKEW_MAP.keySet().contains(ACTIVE_INDEX[0])) {
                    SKEW_MAP.put(ACTIVE_INDEX[0], new HashMap<>());
                    SKEW_MAP.get(ACTIVE_INDEX[0]).put(0, new ArrayList<>());
                    ACTIVE_SKEW_LIST[0] = SKEW_MAP.get(ACTIVE_INDEX[0]).get(0);
                }
