Type specific java.util.List.toArray() [duplicate]

Question

I have this code:

java.util.List<String> result = new java.util.LinkedList<>();

And have added some strings to it.

But I want to return a String[]. Ideally I'd like to write

return (String[])result.toArray();

But I get a casting error at runtime. (Cannot convert Object[] to String[]). Is there a way round this that doesn't involve manual element by element copy?

Use the overloaded method toArray(T[] arr).

Try this:

return result.toArray(new String[result.size()]);

Exactly for this there is the toArray(T[] arr) method so you can pass it a String array
