> Sure. There's nothing Java can do that can't be done by hand. in practice there is. For example, the JVM can inline virtual calls to code that was loaded at runtime (even if that’s third party code for which you don’t have the source code). To do that by hand, you more or less would have to write something like the JVM yourself.
