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 that?
String commaSeparated = "item1 , item2 , item3"; List<String> items = //method that converts above string into list??
Convert comma separated String to List
List<String> items = 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.
Please note that this returns simply a wrapper on an array: you CANNOT for example
.remove() from the resulting
List. For an actual
ArrayList you must further use
