Incompatible types when converting List to String array

Question

I seem to be getting an error when trying to convert a list to an array, this is my code

List text = loadFile(pathName); String[] convertedData = text.toArray(new String[text.size()]);

The error I'm getting is:

incompatible types: java.lang.Object[] cannot be converted to java.lang.String[].

Not really sure why and if anymore information is needed ill be happy to post, any help would be greatly appreciated.

If loadFile(pathName) returns a list of String write List<String> text = loadFile(pathName); — someone_somewhere

Use a generic List of Strings:

List<String> text = loadFile(pathName);

and make sure that the loadFile method returns a List<String>.

The problem is that you're calling the parameterless overload of toArray(), which returns Object[]. You can't assign an Object[] to an String[] variable. To fix the problem do this:

 List<String> text = loadFile(pathName);
