How to split string with trailing empty strings in result?

Question

I am a bit confused about Scala string split behaviour as it does not work consistently and some list elements are missing. For example, if I have a CSV string with 4 column

Answer 1

I believe that trailing empty spaces are not included in a return value.

JavaDoc for split(String regex) says: "This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array."

So in your case split(String regex, int limit) should be used in order to get trailing empty string in a return value.
