I presume WeatherData.getData() should be going into some Data class that has multiple properties (using the , as a delimiter) instead of what OP is doing and just using the String
I mean, unless it's explicitly specified, one can still argue. For fun, that is. I did it a few times with stuff like using maps when the task said I couldn't use loops. Didn't really get into trouble since there was a proper solution ready as well.
To be needlessly pedantic on this joke, answer07 in itself is not an object, but a class, a blueprint for objects. An instance of that class would be an object. Calling the static function main does also not create an instance of the class in the class loader.
To expand on that you can never instantiate an object of type answer07 since it's a static class.
(For the students here the "static" modifier means "it's on the class, not the object". Non-static will only be accessible as a "obj.whatever" but static is accessible by "Class.whatever")
