Java 1.4.1 Final... Soon

Full Text for those interested:

1) Java 1.4.1 will be released on March 3rd

2) Apple has reduced the number of custom classes from somewhere in the
hundreds down to about 80.

3) The new HotSpot virtual machine that is a part of this release has
improved garbage collection that works in three stages, with items that are
used more often moving into stages that are less likely to be erased from
memory. The third stage is reserved for the most used items and is unlikely
to be "collected with the other garbage" unless memory gets very low. Apple
has added a fourth stage called "immortal" that will store items that are
the most often used objects and not allow them to be destroyed. This will
help to speed up the system.

4) The Java VM will be "always on" and will actually start up with the
machine AND load some objects into the immortal area. This should speed up
the launching of Java programs substantially.
5) Apple has implemented shared jars (not sure of the name) so programs will
now be able to share resources instead of each java program launching its
own VM will the same base classes as another program that is running. This
will reduce the overhead required by Java.

Thanks to Frank.

This is great news! Java 1.4 has been released for what, a year now? Unless you're using regexp and/or assertions, 1.3 will do just fine. Nonetheless, it's nice to know OS X will finally have the latest Java SDK. Let's hope Apple will keep future Java updates for OS X on or near Sun's release timeframe.

Hopefully, IntelliJ and JBuilder 8 will finally be available for OS X!

JBuilder never worked for me, I hope JBuilder 8 will be available soon and will be a working version.

Ouch, won't that hurt the people out there with low powered machines?

Personally I can't wait! Bring it on!

I am using Java 1.4.1 on a G3 imac 600mhz- 512mb of ram, I'm not sure if you consider that low powered, but I haven't experienced any slow downs

also.. if you are wondering why it was delayed try the developer release

i am a complete newbie to java, but in our class i use 1.4.1 on my compaq laptop, saving notepad edits in the bin and compliling thru DOS...i think

how does one do the process for macs?


just curious

I really like the free development tools that come with Mac OS X. Their project builder environment can be used to edit and compile pure Java applications. It is a much nicer editor than notepad. Plus, since Mac OS X is built on UNIX, the terminal window is much better than a DOS prompt.

If you pop over to Apple's developer site, you can find more information about how to develop pure Java applications under Mac OS X.

thanks for the tips:)

JBuilder is great, but NetBeans also works well on OS X -- and it's free.

The closest you will come to what you describe is to use TextEdit to work on your souce files (saves as Plain Text of course), and running javac from the terminal (/Applications/Utilities/Terminal).

The command line options will be almost identical to those on Windows and exactly identical to Java under any UNIX-type OS. One notable difference is that under Windows you have been separating paths in your -classpath argument with a semicolon. On OS X you'll separate them with a colon.
