It all depends on the underlying platform and the actual JVM implementation, but some things come to mind: faster 64-bit integer arithmetic (think long variables, which are 64-bit wide); access to larger memory space; potentially more CPU registers available to the JVM, which might lead to faster execution speed (on AMD64, compared to i386); etc. You can expect the 64-bit version of a vendor's compiler to generate the exact same bytecode (.class, .jar, whatever) than its 32-bit counterpart. The compiler just turns your source code into platform *independent* bytecode. > On 1/8/07, Javier Kohen <[EMAIL PROTECTED]> wrote: > El lun, 08-01-2007 a las 15:58 -0600, vamsee movva escribió: > > I think those class files are generated on 32-bit machine > with 32-bit > > JVM > > The Java compiler generates the bytecode, not the JVM.
