Java Forum / General / February 2005trouble installing BlueJ - no Java system installed
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)? >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 > Visiting the webpage, it said: > "You should download J2SDK from the Sun Microsystems Java website and > install it.

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.

The Sun web site seems completely useles at the moment. I guess it's being swamped with downloads of solaris 10. Steve >Anyway - 1.5 looks prettier. > >Steve 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. > Is 5.0 the new number for 1.5? I think I read that. 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. /Thomas  SignatureThe comp.lang.java.gui FAQ: ftp://ftp.cs.uu.nl/pub/NEWS.ANSWERS/computer-lang/java/gui/faq > > Should I download 5.0 (Core) or 1.4.2 (Desktop)? > > I would suggest that you use SDK version 1.5.

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...;-) -- chris >In all probability using the 1.5 version won't cause any problems. 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. > Need I download the package that comes with Netbeans? 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. /Thomas SignatureThe comp.lang.java.gui FAQ: ftp://ftp.cs.uu.nl/pub/NEWS.ANSWERS/computer-lang/java/gui/faq > Visiting the webpage, it said: > "You should download J2SDK from the Sun Microsystems Java website and > install it.

Depending on what BlueJ wants, download 5.0 (1.5) or 1.4.something. /Thomas SignatureThe comp.lang.java.gui FAQ: ftp://ftp.cs.uu.nl/pub/NEWS.ANSWERS/computer-lang/java/gui/faq >> Visiting the webpage, it said: >> "You should download J2SDK from the Sun Microsystems Java website and [quoted text clipped - 7 lines] > > /Thomas 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 Steve > I looked, and couldn't find any mention of version 1.5 on the BlueJ > web site, which is very odd. 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. /Thomas SignatureThe comp.lang.java.gui FAQ: ftp://ftp.cs.uu.nl/pub/NEWS.ANSWERS/computer-lang/java/gui/faq >> I looked, and couldn't find any mention of version 1.5 on the BlueJ >> web site, which is very odd.

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.
