Hi There,

I am trying to find out the relative costs of bitshifting vs casting in java
(on primitive types).
Can anyone give me any suggestions?

Cheers Jochem

Why don't you write some small test programs to figure it out for your
environment? We don't know your VM, we don't know your OS, we don't
know the purpose for this (this isn't by any chance homework?)

     supposed to spend some time with YOUR problem, you are supposed to
     spend some time to find the right news group.
