----------------------------------- Spartan_117 Thu Jul 28, 2005 11:05 am SDK vs JRE ----------------------------------- maybe im stupid and i should know this, but i dont the exact difference between these two. I know to program in Java all i need is the SDK, but what exactly is JRE needed for? also do i hav to get both of these updates (i found on the Java site)? J2SE 5.0 J2SE 1.4.2 ----------------------------------- wtd Thu Jul 28, 2005 11:26 am ----------------------------------- The Java SDK includes the JRE. SDK: Software Development Kit. This includes everything you need to write Java programs. JRE: Java Runtime Environment. This includes everything you need to run Java programs. Java 1.5.0 is newer than Java 1.4.2. You only need 1.5.0. ----------------------------------- Spartan_117 Thu Jul 28, 2005 12:11 pm ----------------------------------- hmmm now i understand.. but im wondering why anyone would get JRE on its own. and what about those updates, do both need to be downloaded? also, is JDK the same as SDK? ----------------------------------- wtd Thu Jul 28, 2005 4:44 pm ----------------------------------- hmmm now i understand.. but im wondering why anyone would get JRE on its own. and what about those updates, do both need to be downloaded? also, is JDK the same as SDK? Yes, JDK is usually short for Java Development Kit. Haven't heard that term in ages, though. I've mostly heard Java SDK recently. No, both do not need to be downloaded. People would have just the JRE because all they care about is running Java programs, like applets on web sites. Far fewer people (but still a substantial number) actually write Java programs. ----------------------------------- [Gandalf] Thu Jul 28, 2005 5:04 pm ----------------------------------- People get JRE because most people want to have a java compatible browser (use java applets and that kind of thing) while not so many people program in Java (SDK). Isn't SDK 5.0 the same thing as SDK 1.5.0? You only need to download the newest version, at all. *edit* Dang, I didn't refresh in a while. Oh well. ----------------------------------- wtd Thu Jul 28, 2005 5:06 pm ----------------------------------- "]Isn't SDK 5.0 the same thing as SDK 1.5.0? Yes. Sun sucks at naming things. ----------------------------------- Spartan_117 Fri Jul 29, 2005 8:30 am ----------------------------------- "]Isn't SDK 5.0 the same thing as SDK 1.5.0? Yes. Sun sucks at naming things. lol. i noticed that, why the hell do they hav JDK 5.0 and SDK 1.5.0???? it confuses the shit out of ppl. ----------------------------------- Aziz Fri Jul 29, 2005 8:42 am ----------------------------------- It was a significant change from 1.4, and (I've read this on their site) that's the new way of naming the kits (Java SDK 5.0 is the name, Java SDK 1.5.0 is th technicall version). At least that's may understanding, and the Lord knows I've been wrong before...oh so many timea.... :lol: ----------------------------------- Spartan_117 Fri Jul 29, 2005 11:17 am ----------------------------------- lol, so it wont matter if i get JDK 5 or SDK 1.5.0 rite? ----------------------------------- Aziz Fri Jul 29, 2005 12:07 pm ----------------------------------- Should be the same thing. Is there too different downloads? What's the page that you're trying to download it from...? Here's the correct page: https://jsecom15b.sun.com/ECom/EComActionServlet;jsessionid=BB977595FCDE50BB55F29FCC97F6A493 ----------------------------------- Spartan_117 Fri Jul 29, 2005 12:47 pm ----------------------------------- Should be the same thing.

Here's the correct page: https://jsecom15b.sun.com/ECom/EComActionServlet;jsessionid=BB977595FCDE50BB55F29FCC97F6A493 Well i went to a website (First Cup of Java: http://java.sun.com/docs/books/tutorial/getStarted/cupojava/win32.html) and it says i need the SDK at this website: http://java.sun.com/j2se/1.4.2/download.html But then while browsing throught this website i also found JDK at this link: http://java.sun.com/j2se/1.5.0/download.jsp this is what confused me to death ----------------------------------- Aziz Fri Jul 29, 2005 1:03 pm ----------------------------------- You'll definitly want 5.0, its new version then 1.4.2 ----------------------------------- rizzix Fri Jul 29, 2005 1:05 pm ----------------------------------- ok look. just read the [url=http://www.compsci.ca/v2/viewtopic.php?t=3568]Java Newsflash it explains the naming confusion.. ----------------------------------- [Gandalf] Fri Jul 29, 2005 1:18 pm ----------------------------------- Download the last thing, the other site is outdated. So was 1.4.0 called 4.0 too? ----------------------------------- rizzix Fri Jul 29, 2005 1:22 pm ----------------------------------- no the 5.0 thing started out with version 1.5.x in addition to that, things have changed from 6.0 onwards... it is no longer J2SE 6.0, but Java SE 6.. simpler? yes i thought so too. ----------------------------------- Spartan_117 Fri Jul 29, 2005 3:21 pm ----------------------------------- So JDK 5.0 is what i should download? ok thx
