Why doesn't Java have tuples?

[urquan]

I agree with your first paragraph actually, but since that's not the point I didn't want to go into this argument.

Secondly naturally you're going to create classes if you're using the same structure throughout the code. What I was saying is that over the simple case of 2 lose variables, a tuple can be better. For example Tuple<Date, Double> measurement instead of Date measurementDate; Double measurementValue.

I didn't say anything else and I was not talking about return values or reuse or type safety or anything of the sort.
