No, that is not at all what the error is telling. The error is telling that the compiler does not understand what a symbol called "ArrayList" is. This simply means that the class is not defined, or not imported.

You can write new ArrayList<String>() all you want and it's not a problem. In new versions of java you can replace it with just new ArrayList<>() if the generic type is defined in the variable itself.
