Convert comma-separated String to ArrayList

Question

Is there any inbuilt 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 that?

String commaSeparatedString = "item1 , item2 , item3";
method that converts above string into list?

Answer 1

List<String> alist = Arrays.asList(str.split("\\s*,\\s*"));

The above code splits the string on a delimiter defined as: zero or more whitespace, a literal comma, zero or more whitespace which will place the words into the list and collapse any whitespace between the words and commas.
