If it is just certain library items that you need you could download the 1.5 source and try manually adding the classes you need to a specific project. It could turn out to be a really good learning experience for you. This will depend on which parts of the language you need.

click on a program for a description, and I would just get rolling arrows...
have had to use the excite guide for now... poor me.
actually, just checked, and the description loaded once but didn't update for any other shows picked...
Anyone updated willing to check?
Ummmm, that is done using Flash, not Java. And I don't have any problem with it working in Safari on my machine.

Okay, so there is one big school doing it too. The department head has probably never worked in the real world and has no clue that you're going to have to re-learn many things before you start working some place outside of the school. Otherwise, you'll be singing "but it's available in" along with "we didn't learn to do work with that" with some choruses of "this place is so backward".

exactly. a pre-release of a new version of a programming language does not make for a learning standard. look at all of the people who still code using c. i think that some of the people on this forumn need to distinguish the difference between application software features that are missing (such as msn on the mac sucks ... ) and development language iterations that have zero impact on them ... what feature in java 1.5 is it that they need so badly??? oh yeah, right, safari won't work with that new site unless java on the mac can support primitive typed collections ...
We're still doing everything in 1.4.2. They'll probably switch to 1.5 next year, but while it hasn't been fully released yet, they're sticking with the current version. By the way, has anyone had any problems with IDE's after install? 1.4.2 completely messed up my NetBeans, I'm wondering if this will have any effects.broken_keyboard said:
Yahoo Chat Rooms
Everytime I use Java in Yahoo Chat rooms it constantly kicks me out and the screen constantly goes in and out of the chat rooms. It never stays in a chat room just gives an error message: "Yahoo Chat has been disconnected would you like to reconnect? YES or NO" - this message runs over and over.
This is a major problem that has been noted on MANY Forums - Most MAC users HAVE to use a third party program to use Yahoo Chat.
I was hoping that this released fixed it and it still does the same thing.
Yes - In my Safari Preferences - Java is all checked ON.

I just tried Safari and Firefox and the Yahoo! Messenger application on my other system which does not have the Java update and I see the nasty behaviour the Safari gives you. It's somewhat better behaved on the upgraded system but does not work past the first 10 seconds giving a "General Chat Error" message before the reconnect message.
I'll have to try the old machine again once I've updated it.
Did you try Firefox or Mozilla or Camino? You may need a 3rd party plug-in but one of those should work, along with Update 2.

This is exactly correct. Most real-world systems won't be updating to Java 1.5 (or whatever it is called) for AT LEAST 6 months after FINAL release. And even that is rather optimistic. Twelve months is a more likely minimum.
Fact is, real people running real systems are NOT on the bleeding edge most of the time for one simple reason...stability. A second valid reason is that the new version rarely offers so much more that is compelling without re-writing large chunks of code anyway, that it is not economically worth it.

I used to have to use my PC to check out the progress of my bus using bus view http://transit.metrokc.gov/oltools/busview.html because it would either not open at all, or even if it did would be all messed up, but now it fires up quicker than on my PC.
One less reason to use my PC is a good thing!
I have been having problems with my computer waking up from sleep mode. I've repaired permissions and my system has been acting pretty strange after the last two updates.
Anyone else experiencing these problems?

Java fix....
Kasel... are you running the latest update 10.3.5?? I had loads of wake up problems on my PB17" before 10.3.5 but now it works like a charm...

schools
i won't have to worry about it at my university. nearly all the cs faculty are mac users.
what are we are going to be teaching first year kids??? IIRC, my 100 level courses were learning the OO basics, not concentrating on data abstraction classes and such.. why does it matter if they use 1.5 or 1.4.2?
once we got to the 300 level, most courses stopped using java and went to c and c++..

Yes as a matter of fact I am. I keep my system up-to-date. Everything worked like a charm before this last update.
Yay
When using the Java applets for playing loops of the NOAA (weather/hurricane) satellite images, they work great now. Previously they would hang Safari (requiring a force-quit). It's not perfect yet, but to my eyes Java on the Mac (specifically applets) is steadily improving. There are very few sites I go to that don't work anymore.

Remember that things like this (ports of an existing application/development platform/etc. by a company other than the creator) always have two parts:HiRez said:
1. Bugs in the original codebase (these get fixed by the original creators, and the changes get handed down to the porters).
2. Bugs specific to the port (these get fixed by the porters, and the changes don't get handed off to anyone since they don't affect anyone else).
Remember that the cause of your problem could be #1, #2 or both #1 and #2. #1 problems Apple can't do much about, but #2 problems Apple can fix fairly easily once their testers identify the cause.
Well I guess you can add 2 big schools to this, as I will also be using Java 1.5 next semester. I guess the thing you "professional programmers" don't realize is that we students in intro programming courses are generally not graduating this year. Most students taking intro programming now will not be in the "real world" (except for internships) for another 2 or 3 years. If we follow your logic completely then we should all be learning Fortran since some legacy programs are out there. My professor's general outlook is that the class is Intro to Object-Oriented Programming and Java just happens to be the best cross-platform language to teach it. In addition, he thinks that 1.5 adds some features that are useful to the concept of object-oriented programming, and will teach those in the second semester. Does that sound "crazy"? I don't think so. I'm sure Java 1.5 will be well established when I graduate . . . in 2006.
If you still think using Java 1.5 is stupid, then you must also think Apple is stupid since they release the Java 1.5 pre-release to developers. I just wish they would legal make it available for other. In addition the requirement of having to use Apple Tiger, to run Sun Tiger (Java 1.5 code name), just makes it more complicated to use a Mac since you need to somehow get the developer edition of Tiger (become a criminal and use BitTorrent) and then you need to make your system dual-bootable unless your crazy enough to use Tiger preview for all your work.
In the windows world you can have multiple Java versions installed and your IDE can choose which one to use, why can't Apple allow these choices. Is it really a technical hurdle or an attempt to get more money out of end users.

You're missing the details but suffice it to say that it is careless to attempt to use pre-release software on students. If you don't know what the outcome is going to be, how can you know if it's right or not?
For Apple to release software prior to general release for testing purposes is not stupid. It helps Apple and, possibly the development community, work out problems. I can't imagine the majority of developers being so careless as to base a product on a pre-release version of anything, no matter how wonderful it is. (How long did we use MetroWerks CodeWarrior before it became something other than a developer release? 3 years, maybe?)
Yes, I believe that FORTRAN (not Fortran) 77 has a lot to teach you and yes, there are a lot of scientific applications still out there. You should also be learning COBOL 85, C 99, PL/I, Ada 95, and Modula-2 for a good background in procedural languages and efficiency. Computer Science students should probably also study LISP and Prolog to learn simple AI.
If your instructor is so concerned about object-oriented principles, he should be teaching Smalltalk, not Java, since Java is still a hybrid language, though more pure than C++. Java is a nice language and I currently do 100 percent of my coding using it but it is not a panacea.
Exactly, they released it to developers, not students in intro programming classes.phasornc said:

Excellent points... I think a well rounded student should study many different languages... That way, they can get used to solving problems, not solving problems in Java -- there is a difference. Plus, all the world is not OO, and neither is OO the best solution for all problem spaces. You'd be impressed how fast compiled COBOL runs on the mainframe. I'd really hate to see our university CS departments churning out "coders", because you might well have gone to a trade school and saved yourself a ton of money.
Knowing how to write software using the Java 1.5.x SDK is worthless if you can't write sofware in Java. Or C++. Or COBOL. Does that make sense to you college kids?

It doesn't make one iota of difference which language you learn to program with. It is the principles involved in writing clean, effective software that are important. If your teacher is focusing on features specific to 1.5 to teach you OO then he probably isn't really doing a good job of teaching you OO.
All I can say is, come back and chat with us when you finish that degree. Personally I don't put a lot of stock in the opinions (on CS matters) from people that haven't even taken the introductory courses. The school I graduated from consistently has the same number of students enrolled as pre-CS (this means they haven't completed intro to programming with a C or better) as they do CS (the remaining 3.5 semesters). And those that actually graduate are a much smaller percentage.
If you do become a good computer scientist then it will not matter if you know the latest and greatest. Any computer scientist worth their weight in salt can learn new languages and/or language elements very quickly because they already understand the underlying concepts of how things work.
Finally, I do have multiple versions of Java on my system.
