some sort of Java for a Amiga

Java Grinder is not a JVM, but instead translates byte-code from Java .class files into native assembly code much like a JIT or an "ahead of time" compiler.

Wondering how usefull this is?

Java Classpath is the runtime library. It's the hard part. Bytecode translation isn't easy either but you need both to run real Java applications.

I saw this on OSNews and thought it was pretty damn cool.

Check out the code samples:

I'm definitely going to have a play with this and see if it's an option for my next game, and what the speed penalty is.

That's really nice..

(would even love it more, if it were C#, since I use that for all of my game dev tools..

)

It's cute to call that "Java" but it's only a subset of the language, the API is completely custom by the looks of it and you won't be able to use any of the platform tools such as the debugger.

Really cool technology though!

The demo is coded in Java and compiled by the standard JDK javac. The API for sure isn't J2SE, but neither is J2ME or Android.

Really nice job, Mike!

Amiga needs more modern stuff like this...

Awesome stuff Mike!

It constantly amazes me what demo coders are extracting from the likes of the C64 and standard A500/1000 these days.

Thanks! And thanks for posting and discussing the project

.

Speaking of C64... one of my friends (Joe Davisson) extended Java Grinder for 6502 and created a C64 and more impressive a full Atari 2600 game. There are some links on the Java Grinder main page:
