QUOTE(kuberan_swe @ Nov 18 2007, 01:47 PM)  People please let me know what is the exact difference between JDK 6 and J2SDK. Guess both of these installations belong to Java 2. Hi, This is due to Sun's naming convention changing as they progressively bring Java into a wider and stabler platform. To follow the history : - The first releases of Java in the early 90's was labeled 1.0 , then 1.1. We talked then about a JRE 1.1 and JDK 1.1 , for Java Runtime Environment and Java Development Kit. - When it came to Java 1.2 , changes were so radical that the brand name for Java platform 1.2 was 'Java 2'. The JRE and JDK then became J2RE 1.2 and J2SDK 1.2 ! (for "Java 2 Software Development Kit, version 1.2"). This was the beginning of a little confusion... - This continued like that until version 1.4.x. - When introducing platform 1.5.0, Sun thought it a little weird to always stick to a '1.x' version number, even for major changes, like in 1.2. This made people think that version 1.5.0 was merely an update to version 1.0, where I beleive not a single line of code has survived... they then decided to drop the initial '1', and to call the new version 5.0 instead of 1.5.0. However, 1.5.0 would also remain for technical compatibility reasons. Version "5.0" is the product version, while "1.5.0" is the developer version, and the whole still being labeled as 'Java 2' !! We then had a 'J2SE 5.0' for the name of the platform, the runtime and development kit being now reverted to JRE 5.0 and JDK 5.0 (instead of J2SDK and J2RE) due to developer popularity. - For platform 1.6, Sun then dropped the last digit, to call it 'Java 6' , and dropped the 'Java 2' concept. The platform is now called 'Java SE 6', with a 'JDK 6' and a 'JRE 6'. Note that the 'developer version' is still 1.6.0, this is what you would get from doing java -version, and the name of the installation directory... But, to answer precisely to your question : - JDK 6 is the Java Development Kit for Java Platform 6 (developer version 1.6.0) - J2SDK is a Java Development Kit for an unspecified version, there should be an additional version right after. However, if it is really called 'J2SDK', it should technicaly mean that it is comprised between 1.2.x and 1.4.x, but as everybody is confused, this is not a guarantee... Hope this helps Antoine

What's The Difference Between 64 And 32 Bit?
Buying a new computer. (9) Hey everyone! I'm going to be buying a new laptop in a few months, and I am very confused
about one thing: AMD manufactures a LOT of 64 bit processors, while Intel almost never does.
I'm clueless when it comes to processors, and I'm concerned because I haven't really
been paying attention to processor specs as much as HD and RAM, even though those are the cheapest
and easiest to switch. Does anyone have any good tips about processors? I'm mainly wondering
what the difference between 64 bit and 32 bit is, but other than that I also want to know i....

"Support Our Troops" ribbon on it. Seems as though every community has it's own little project

most part its the same thing. there will be a 20GB for $499 and 60GB for $599, but it

(god, pure good, alah, whatever u name it...) that represents the highest good to all of them. I
think that a mountain is a very good example to explain how these religions are connected: There are
inumerable ways to the top of the mountain and each of this ways is a certain religion but al....
