Re: Java is faster!

Show all headers | View raw

Since Java is typesafe, and this typesafety goes
vary far, recently, after much time, I have
even created a runtime error when assigning
an array cell, so the component type of the array
didn't match the element type.

I think there is a general limit. This typesafety
is still ingrained in the runtime. Although casts
are highly optimized, they don't go away. I recently
made some other experiments, and bumpted my head
speed wise just because of the many casts I needed.

So if all is well typed, no casts and a lot of primitive
types, I guess you get speed. But if you use more
generic data structures, I see some problems just
because of the casts, although some caching techniques
are used inside the JVM.(*)

(*) There are tons of patentsn by Sun etc.., but
I don't know whats currently going in a JVM on.
Newest JDK allows methods in interfaces, etc..
JVM getting complexer from release to release.
