Is it faster to access final local variables than class variables in Java?

Question

I\'ve been looking at at some of the java primitive collections (trove, fastutil, hppc) and I\'ve noticed a pattern that class variables are sometimes declared as fina

Answer 1

it tells the runtime (jit) that in the context of that method call, those 3 values will never change, so the runtime does not need to continually load the values from the member variable. this may give a slight speed improvement.

of course, as the jit gets smarter and can figure out these things on its own, these conventions become less useful.

note, i didn't make it clear that the speedup is more from using a local variable than the final part.
