Why do I get an UnsupportedOperationException when trying to remove an element from a List?

Question

I have this code:

public static String SelectRandomFromTemplate(String template,int count) {
   String[] split = template.split(\"|\");
   List         


        

Answer 1

I've got another solution for that problem:

List list = Arrays.asList(split);
List newList = new ArrayList<>(list);

work on newList ;)
