trouble installing BlueJ - no Java system installed

[Tim923]

Visiting the webpage, it said:
"You should download J2SDK from the Sun Microsystems Java website and
install it. You can get it here: java.sun.com/j2se"

Should I download 5.0 (Core) or 1.4.2 (Desktop)?

We will be writing small programs for a low level Java course in
Windows (not Unix).

Unless you have a need for the new capabilities in 5.0, I would
recommend 1.4.2

I would suggest that you use SDK version 1.5. I really cannot find it on
the web site now, but I know that bluej version 2.0 added support for
java 1.5. If ypu are running a java course, you will want to be able to
teach the latest syntax - generics and the like that java 1.5 introduced.

Anyway - 1.5 looks prettier.

P.S.
The Sun web site seems completely useles at the moment. I guess it's being
swamped with downloads of solaris 10.

Is 5.0 the new number for 1.5? I think I read that.
I'm taking the course (not the professor). Maybe I'll ask him.

In all probability using the 1.5 version won't cause any problems.

BUT !

The "latest" stuff in Java 1.5 (or Java 5, if you prefer) will be of less than
zero value to new programmers.

Especially, it will have negative value to anyone using BlueJ, since their
teacher (apparently) has the sense to realise that OO is the important
concept-set to focus on.

Generics do /not/ belong in a beginners class.

('I'm tempted to go father than that, but this is not the occasion...;-)

Need I download the package that comes with Netbeans? Is there a
faster website to download Java 5. Sun's is like 2KB per second.

Does the BlueJ web site say BlueJ runs with 5.0 (which is equal to 1.5,
don't ask ...), or 1.4.something. Depending on what BlueJ wants,
download 5.0 (1.5) or 1.4.something.

Yes 5.0 is Sun's marketing stunt for renaming 1.5.

I'm taking the course (not the professor). Maybe I'll ask him.

Sounds like a good plan.

No, netbeans is BlueJ for adults . If you want to use BlueJ you don't
need netbeans. All you need is a JDK, also called Java 2 SDK, or J2SDK
for BlueJ to run.

BTW: Please consider posting beginners questions to comp.lang.java.help.

Is there a
faster website to download Java 5. Sun's is like 2KB per second.

No, Sun does not allow the redistribution of the JDK.

I looked, and couldn't find any mention of version 1.5 on the BlueJ
web site, which is very odd. But the Help->Check Version menu from my
current BlueJ install says the following...


Your current BlueJ version is 2.0
The most recent BlueJ version is 2.0.4

New in version 2.0.4
--------------------
BlueJ 2.0.4 is a bug fix release. It fixes a bug from version 2.0.3
that caused problems with installations in paths containing spaces.

New in version 2.0 (among other things):
------------------------------------------
- support for J2SE 5.0
- support for generic classes in interface
- specific enum support
- interface improvements
- key navigation of class diagram and object bench
- editor improvements
- improved extension API
- addition of Code Pad for Java text evaluation
- bug fixes

See the right side of

http://www.bluej.org/download/download.html

The box which is labeled "System Requirements" So 1.5 (aka 5.0)
should indeed work.

LOL! I found it when I went to collect the update, thanks. But I looked
all over BEFORE going to the download page, as one might if they were
wondering whether it was something they even wanted to download.

I confirm that it DOES work with 1.5.
