The OP said they were ArrayLists, not arrays. String[] should be List<String>, and the method can actually be built with generics to support any kind of list. I'll add an answer to show how.

@tintinmj Arrays.toString() adds ,, [ and ] to the output, something that OP does not want.

I think the whole code block inside getArrayContent method can be substituted with return array.isEmpty() ? "-" : Arrays.toString(array);
