replace an emptyArray and computeIfAbsent instead

- some methods should return an empty array.
- avoid the result of a java.util.Map.get()
  against null before proceeding with adding
  or changing the value in the map.
- Declaring a variable only to immediately
  return or throw it is a bad practice.
