Java - Simple way to put LinkedHashMap keys/values into respective Lists?

Most collections accept Collection as a constructor argument:

List<String> keyList = new ArrayList<String>(map.keySet());
List<String> valueList = new ArrayList<String>(map.values());

For sure!

keyList.addAll(map.keySet());

Or you could pass it at the time of creation as well

List<String> keyList = new ArrayList<String>(map.KeySet());
