But is it something people actually type? I haven't played with Java for almost ten years now but I do C# for a living which is pretty similar and I can't remember the last time I had to type something that long, Visual Studio does it for me. I can see the point if you say it's longer to read but it's also much clearer, isn't it?
It's kind of a misnomer too, because only the second circle is typed for you so you had to type Circle at least once... which is the same as if you were typing var. So it's not only not saving you much effort it's uglier. And with more complex types it's downright evil (to not use var).
