As other answers have stated already, to use the first element in a list, you would call the List.get(int) method.

someList.get(0);

In your code, in order to iterate over the String array in the first list index, you would want something that looks like:

for( String str : s.functie(arg).get(0) ) {
    //Do something with the string such as...
    System.out.println(str);
}
