Java Forum / General / January 2006java on Mac
Hi. I`v read a lot of how efficient and in general brilliant is java on Macs on apple`s web sites, that its implementation is specially optimized for OS X, it works faster and uses less memory, only superlatives, but I know that i can`t believe in everything what is written in such advertisments... So I have question to you, do you have any experience with Java on Macs? What can you say about it? is it good choose? I`m asking, because I`m going to change my laptop 15,4" into something smaller, and I`m dying for (new)iBook 12", of course I`m not gonna program on it all the time, I mean, I`m gonna use it as mobile machine for programing... thanks for help Pozdrawiam Brzezi  Signature[ E-mail: brzezi@enter.net.pl ][ ] [ Ekg: #3781111 ][ ] [ LinuxUser: #249916 ][ ] > I`v read a lot of how efficient and in general brilliant is java on Macs > on > apple`s web sites, that its implementation is specially optimized for OS > X, > it works faster and uses less memory, only superlatives, but I know that i > can`t believe in everything what is written in such advertisments... Faster is wrong as far as GUI operations. An example is at www.segal.org/java/CanvasTable3/. Apple has fixed a huge number of bugs in recent months but the GUI slowness problem is still there. > > I`v read a lot of how efficient and in general brilliant is java on > > Macs on apple`s web sites, that its implementation is specially [quoted text clipped - 5 lines] > www.segal.org/java/CanvasTable3/.

Jackson Montgomery, Alabama > And what happens with that example if you do it in Swing instead of AWT? I haven't tried to do a similar Swing program. We do most of our code in a way that supports the full range of Java browser environments. If someone does try with Swing it would be interesting to know of the result. For the hardware I've run it on (G3 450MHz, 256mb ram, OS X 10.4.2), Apple's JVM performs pretty well in my opinion. I haven't used it a lot with GUI apps (I'm keeping that for my 12" powerbook which I am getting soon), but I've had some email spam processing work which I've run under the Apple JVM and for the system it's managed to work quite well. >I`v read a lot of how efficient and in general brilliant is java on Macs on >apple`s web sites, that its implementation is specially optimized for OS X, >it works faster and uses less memory, only superlatives, but I know that i >can`t believe in everything what is written in such advertisments... The one big problem is it usually the Mac is substantially behind Sun in implementing the new features. Now they are on top of things at JDK 1.5.0_05.

They don't provide the needed support for Apple (and others who must produce their own JVMs) to get them out closer to Sun's own schedule. But I believe the 1.5 release came out sooner following Sun's than did 1.4 and its later versions, though I might be mistaken. SignatureSteve W.

Anyone, not just licensees can get hold of the weekly builds. IIRC, Sun used to supply Apple with two on-site engineers. Apple are still consistently a year behind in their final releases (IIRC, 1.5.0 had an early developer-only release).

Okay, I'll bite. Why, exactly, do we suppose the weekly builds for Sun's java are supposed to be magic for Apple's Java? And if the weekly builds for Sun's Java are supposed to be all that's necessary to keep pace with Sun, why would IBM want to set up development for an independent, GPL-ed Java? > Tom Hawtin > -- > Unemployed English Java programmer > http://jroller.com/page/tackline/ Brzezi sez: ... > I`m asking, because I`m going to change my laptop 15,4" into something > smaller, and I`m dying for (new)iBook 12", of course I`m not gonna program > on it all the time, I mean, I`m gonna use it as mobile machine for > programing... Well, G4 laptops suck performance-wise compared to similarly priced Ferraris. So unless you're getting an Intel-based iBook, Java on it is not going to be super fast regardless. (I'm using a 17" PB to code, and it could use a faster chip.) Dima Signature...the mainstream products of major vendors largely ignore these demonstrated technologies...

On the other hand, the Intel machines will be getting the -server compiler, so those who are getting MacBooks might have a much happier time.

Yeah, superlatives are superlative. However, I have been using netbeans with jdk5 on a Mac Mini (1.24GHz G4, 512M RAM) and on a Linux tower with a Sempron 2600 (768M RAM) for several months, and the speed of the Mini is not that much slower than on the Linux box. Netbeans on my five year old iBook (300MHz G3, 192M RAM) tends to thrash and crash, but that's not surprising. > So I have question to you, do you have any experience with Java on Macs? > What can you say about it? is it good choose? I like it. Can't say anything about the soon-to-be iNTEL Macs, so I won't. > I`m asking, because I`m going to change my laptop 15,4" into something > smaller, and I`m dying for (new)iBook 12", of course I`m not gonna program [quoted text clipped - 9 lines] > [ Ekg: #3781111 ][ ] > [ LinuxUser: #249916 ][ ] Free MagazinesGet these publications absolutely FREE for up to 12 months.
