Adding to front of List throws?

Question

Trying to use the following to add to the front of a List but throws on the add. The doc says it's supposed to shift. What is the fix or workaround?

List<String> whatever = Arrays.asList("Blah1", "Blah2");
whatever.add(0, "BlahAll"); // <- Throws

Answer 1

You can't add element to a list created using Arrays.asList(). As the documentation explains:

Returns a fixed-size list backed by the specified array.
