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??
Best Answer
Convert comma separated String to List
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 resultingList
. For an actualArrayList
you must further usenew ArrayList<String>
.
