[jdjlist] RE: JVM Overhead

[John Ghidiu]

Stacy,   I would think that there would be, as the first example declares a new instance of MyObject every iteration, which I believe will allocate memory on every pass, whereas the second example will not. However, I cannot say for certain that the compiler will optimize this. Perhaps a simple benchmark would be the best solution? Regards, John John Ghidiu Benderson Development Company Inc.
