[jdjlist] RE: JVM Overhead

[Greg Nudelman]

Funny you should ask!  I just wrote a small program to test the same thing a couple of weeks ago.   I can honestly say that on JDK 1.3 it makes no difference.  I think that the compiler optimizes the code either way. However, IMHO, the second one is more clear to me as a programmer.  I can see that myObject is the object you're going to instantiate/work on for every member of the loop.    Greg   http://www.HotSciFi.com [Greg Nudelman]  -----Original Message----- From: Stacy C.
