Yes and no. In theory a well written Java program will run on any system that has a Java VM. In practice it may not always work.

Yes - and No.Yes, you can develop a very large program purely in binary - it's how we started in this game and the first operating systems and everything else were written that way.But...it's slow. Very slow. That's why one of the first things written in binary was a basic assembler, to...

Native code: "Write once, run everywhere" - is it possible?

31 Dec 2014 by Richard MacCutchan

See my response to your repost of this question.And no, you can certainly not run native Windows code on an Android device. Android uses Java, but its program structure is very specific to the Android OS so it will not run on other systems.

Managed code vs markup hybrid code: Performance

3 Jan 2015 by Mehdi Gholam

Generally "native code" meaning compiled directly to the CPU instructions is faster, however in some circumstances "managed code" running on a "virual machine" can be faster.So you really have to try and see which works best for your situation.

Those "validations" should be done during the "input" phase; not when you're calculating; that's why it's a mess. You're letting "garbage in".
