Adding comma separated strings to an ArrayList and vice versa

Question

How to add a comma separated string to an ArrayList? My string \"returnedItems\" could hold 1 or 20 items which I\'d like to add to my ArrayList \"selItemArrayList\".

Answer 1

Simple one-liner:

selItemArrayList.addAll(Arrays.asList(returnedItems.split("\\s*,\\s*")));

Of course it will be more complex if you have entries with commas in them.
