A one-liner code to convert comma-separated Strings to List in Java

No talking! Let’s just do the code.

// String that is comma separated 
String listOfUserIds = “10,11,12,13”;
// The magic that converts it to list
List<String> userIds = new ArrayList<String>(Arrays.asList(listOfUserIds.split(“,”)));

To convert the List back to String:

userIdsLists = userIds.join(', ')
