Why would you ever implement finalize()?

Question

I\'ve been reading through a lot of the rookie Java questions on finalize() and find it kind of bewildering that no one has really made it plain that finalize()

To highlight a point in the above answers: finalizers will be executed on the lone GC thread. I have heard of a major Sun demo where the developers added a small sleep to some finalizers and intentionally brought an otherwise fancy 3D demo to its knees.

Best to avoid, with possible exception of test-env diagnostics.

Eckel's Thinking in Java has a good section on this.
