I use Java only when I have to, like helping students with projects, or sometimes a quick visualization in Processing. So my disclaimer is that I'm not super familiar with the language. The other day I was reading triangle mesh data into Processing and the data seemed to have an error somewhere. Part of finding it was checking for duplicate edges. So I wanted a Set of tuples of reals. Hilarity ensued. That Java didn't have tuples was a minor annoyance. The amount of boilerplate needed to make what was basically a struct of two floats Set'able was ridiculous. I suspect Java is not as terrible for big projects.
