First of all, questions that will be uncontroversially deleted aren't a big concern. (Delete votes can be cast two days after closing.)
They should, however, still be tagged appropriately – plus what appears uncontroversial to me and you maybe actually isn't, and some questions (i.e. not this one) might end up staying. Tagging [java] does little harm here, as the tag is so popular that this question will get lost in it, but [untagged] is a candidate just because the system requires at least one tag. (I've been planning to use [untagged] for exactly this situation, but haven't yet found a situation where I could think of nothing else.)
In general, tags are inappropriate for the intention or purpose of the poster rather than the content ("meta tags"), with how the question should be closed (e.g. [offtopic]), and where the question should be moved (e.g. [belongs-on-*]).
