How to convert comma-separated String to List?

Question

Is there any built-in method in Java which allows us to convert comma separated String to some container (e.g array, List or Vector)? Or do I need to write custom code for t

Answer 1

There are many ways to solve this using streams in Java 8 but IMO the following one liners are straight forward:

String  commaSeparated = "item1 , item2 , item3";
List result1 = Arrays.stream(commaSeparated.split(" , "))
                                             .collect(Collectors.toList());
List result2 = Stream.of(commaSeparated.split(" , "))
                                             .collect(Collectors.toList());
