Java for DS

[FAST6191]

For those unaware java is a high level programming language which courtesy of its tendency to be compiled to bytecode and then be interpreted is largely cross platform, it is of special note as it is a fairly high level language (something the DS is lacking in support for) and is now widely taught as part of computer programming courses.

Functions available at this stage are quite limited and it is suggested you aim for J2SE 1.4/version 1.4 of the java language as higher will not work.

java4gba, a java virtual machine and the base for the DS port.

Great developement if you ask me (though I wonder what performance it will get and how much developement will/can be done)

. At least I know a little Java

.

I'd assume it is the Java SE Embedded version that is being ported over. Performance here is definitely the biggest issue, so it will be interesting to see how it goes. If it has a decent amount of the library ported over, this will make homebrew development much easier.

Depends on how many of the DS's features are implemented of course (as now only hello world could work really

) and how much of the libraries. The port is currently a direct port (with slight modifications) of Java4GBA with DLDI support added. It broadens the programming languages the DS support which is always nice but C(++) will of course still have way better performance and this will need a lot of developement. So best of luck to josath

For those unaware java is a programming language a bit like the BASIC of old where you create a script which is then interpreted/compiled at runtime.

No it isn't.

Maybe you're thinking of JavaScript.

Which is why I quoted the wikipedia page

. Fix it fast (lol, sorry for the pun

).

 

[FAST6191]

Sorry that was a bit ambiguous, I will rephrase.

 

[madmk]

Thats good news! Will open up lots of possibilities..

 

[Hellios]

I would much rather see J2ME working on a DS than anything else. Seriously, DS homebrew would explode if j2me was properly implemented.

Not to mention we'd get a decent web browser (Opera Mini > any other Opera product)

But still, this is amazing news!

 

[crafton48]

Finally this is awesome news gonna try porting a few of my apps over to the DS,
do you think that it will be able to use the Ds wifi at all? I mean will we be able to use the standard Java libs for networking or will there be some speical ones written?

 

[Icarus]

Will we be able to play mobile phone games with that when it's released?

I'm all for DS development, but I have a hard time believing Java will run well on the DS. I guess time will tell. Hope something comes of this for sure!

 

[KINGOFNOOBS]

Cool, I took Java, but I don't think it would run nearly smoothly enough..

 

[Mangofett]

in b4 "can i run runescape on teh my ds"

 

[kellyan95]

Can I play Runescape on my DS?

edit: damn you, linkiboy

 

[falcon64z8]

THis is great and all but I was hoping for flash support..

 

[Psyfira]

!

That is all. I didn't even know someone had been working on Java on the GBA. Excellent stuff!

I'd assume it is the Java SE Embedded version that is being ported over.

Potential blonde moment: Java4GBA is built around CLDC, doesn't that imply that it's actually based on J2ME? (and that would make more sense on a portable device)

Don't quote me on this, but I don't see any commercial DS games that have vector graphics. Flash = frame by frame vector animations with code. If anyone gets time to port flash to DS (the latest flash) it would probably run 2 seconds per frame. BUT I do think at the beginning of the DS lifetime (before lites) Natrium42 made a flash player. I think it only accepted a max of 10fps and Flash4.0 without any actionscript. But this is from like a year ago, if not longer, and i don't remember too well.

The flash application in question can be found at http://natrium42.com/blog/?p=36

So what exactly can and can't this DS Java do.

It seems to run basic output and mathematical operations fine. But what else can it do?

I haven't messed with this much, but I will.
