Using the json-lib:
使用 json-lib：
String source = "[\"LankaBell\",\"BillDesk\"]";
List<String> list = new ArrayList<>();
list = JSONArray.toList(JSONArray.fromObject(source), new Object(), new JsonConfig());
(Actually you can use just JSONArray.toList(JSONArray.fromObject(source))but it is deprecated)
（实际上你可以使用 justJSONArray.toList(JSONArray.fromObject(source))但它已被弃用）
Another non-deprecated solution:
另一个未弃用的解决方案：
list = (List<String>) JSONArray.toCollection(JSONArray.fromObject(source))

String string = "[\"LankaBell\",\"BillDesk\"]";
//Remove square brackets
string = string.substring(1, string.length()-1);
//Remove qutation marks
string.replaceAll("\"", "");
//turn into array
String[] array = string.split(",");
//Turn into list
List<String> list = Arrays.asList(array);
System.out.println(list);

String input = "[\"LankaBell\",\"BillDesk\"]";
// net.sf.json.JSONArray
JSONArray jsonArray = JSONArray.fromObject(input);
List<String> list = new ArrayList<String>();
for (Object o : jsonArray) {
list.add((String) o);
}
log.debug(list);
