Java's objects aren't types even though they're mixed up with its type system. Objects are supposed to represent units of computation so anonymous classes aren't absurd.

But the reason why it seems that types without names are absurd is that types are only real for the interpreter or compiler. At runtime they aren't used anymore. So it's absurd that a construct made for humans to understand and describe code starts to become something opaque to human understanding because they're impossible to be named.
