Top Highlights

• a LinkedHashMap maintains the order of elements in the order in which they were inserted.

• this order can be either the insertion order or the access order.

• linkedHashMap.entrySet().iterator().next() returns the first element in the map:

• Entry<String, String> firstEntry = THE_MAP.entrySet().stream().findFirst().get();

• Entry<String, String> lastEntry = THE_MAP.entrySet().stream().skip(THE_MAP.size() - 1).findFirst().get();
