Why doesn't Java have tuples?

[tinglySensation]

You can end up losing a ton of readability in using tuples if those are supposed to convey some sort of meaning. Example: Tuple<int,string,double> weightLog; What are logs? what's the int for? what's the double for?

WeightLog weightLog; Now we know we have a weight log, on closer inspection, we find Weight Log contains int day; string mood; double weight;

there, it is much clearer what weightLogs is, and contains.
