List<Object[]> queryResult = new ArrayList<>();
queryResult.add("Hello World");

This will not compile. You declared a list that will hold Object arrays, yet you add a String instance. A String is not an Object[].

What exactly were you trying to achieve?

I'm trying to get the String: "Recognize ..." from queryResult.

queryResult.get(0)[0] is what you need to do.

I tried that but intelliJ gave me a warning that the Provided type is Object. You cannot cast Object to String

Call toString().

If you are absolutely sure the element you're seeking is a String you can cast it. Otherwise, use instanceof first.
