you can create a List<String> and assign it to Collection<String> as List extends Collection.

final String demoString = "1,2,19,12";

Collection<String> collection = List.of(demoString.split(","));

Guava:

List<String> it = Splitter.on(',').splitToList(demoString);

Standard JDK:

List<String> list = Arrays.asList(demoString.split(","))

Commons / Lang:

List<String> list = Arrays.asList(StringUtils.split(demoString, ","));

Note that you can't add or remove Elements from a List created by Arrays.asList, since the List is backed by the supplied array and arrays can't be resized. If you need to add or remove elements, you need to do this:

// This applies to all examples above
List<String> list = new ArrayList<String>(Arrays.asList( /*etc */ ))

Simple and good,

List<String> list = Arrays.asList(string.split(","))
