In recent versions of Java (1.3 onwards, certainly) the performance of reflection is vastly better than it used to be, and so this is much less of a problem. I suspect you'd be hard-pressed to get a meaningful benefit fromExternalizablewith a modern JVM. Also, the built-in Java seriali...

This tutorial explains how to use the Serializable interface in Java IO to mark a class as serializable.
