So they decide to completely drop the 2 (and the ".0" suffix), and we end up with the "Java Platform, Standard Edition 6 (Java SE 6)" containing the "Java SE Development Kit 6 (JDK 6)" and the "Java SE Runtime Environment 6 (JRE 6)". When version 1.6 come out, someone realized that having two numbers in the name was weird. But instead of reverting their change, they just decide to drop the "2" from the name of the individual products, which now get be "J2SE Development Kit 5.0 (JDK 5.0)" and "J2SE Runtime Environment 5.0 (JRE 5.0)".

The suits also realized that the development community was not picking up their renaming of the JDK.

So now the platform is officially called "Java 2 Platform Standard Edition 5.0 (J2SE 5.0)". However, the "2" was retained in the name. So the Java platform got two versions - the product version "5" and the developer version "1.5" (Yes, the rule is explicitly mentioned - "drop the '1.'). When version 1.5 came out, the suits decided that they needed to "rebrand" the product.

The JDK was officially renamed to "Java 2 Software Development Kit". The default "distribution" of the platform was given the moniker "standard" to contrast it with its siblings. The two products that were part of the platform were also given names:Īpparently the changes in version 1.2 so significant that they started calling the platform as Java 2. If you were a developer, you also knew the version, which was a normal "1.0" and later a "1.1". When Java was first released, it was apparently just called Java. It consists of two products - the software development kit, and the runtime environment. Now you know what they are and why they are there.Ī Brief and Maybe Incorrect History of Java Versions Again, see above.Īfter your install, double check “C:\Program Files\Java” to see both these folders. Remember from above that JDK contains JRE, which makes sense if you know what they both are.

“C:\Program Files\Java\jre7\” (JRE) Keep in mind the above links are for reference purposes only, to show you the step by step method of what it takes to download the JDK. You are now downloading (hopefully the latest) JDK for your system! :).

Click "Java SE Development Kit 7 (Windows 圆4)": (for my 64-bit Windows 7 system).

Click "JDK Download" and visit "Java SE Development Kit 7 Downloads": (note that following the link from step #1 will take you to a different link as JDK 1.7 updates, later versions, are now out).

Here's the step by step links I followed (one step leads to the next, this is all for a single download) to download Java for development (JDK):

JRE = Java Runtime Environment (users need this, this is every computer user today).

#Java se development kit 15 download code

JDK = Java Development Kit (developers need this, this is you if you code in Java).

Both will be installed from the single JDK install, as you will see below. Next, for developers, download JDK, not JRE. Now, let's dive into this "madness", as you put it.Īll of these are the same (when developers are talking about Java for development):Īnd we can assume this will remain for future versions. I am installing the latest Java on my system for development, and currently it's Java SE 7. The tentative end of public updates for Java SE 8 is March 2017, but that end date is subject to change (later, not earlier). In April 2015, Oracle affirmed that it was no longer providing public updates to Java SE 7. But the version 6 (1.6) is becoming antiquated.Įdited : And with another couple of revolutions around the sun, the time has come for the end of support for Java SE 7, too. JDK is the Java Development Kit, JRE is the Java Runtime Environment, Java SE is the standard edition, and so on. Within a given version of Java, this answer remains valid. Oracle says no more public updates to Java 6 after February 2013.

(See also .)Įdited : And the world keeps on turning ( notwithstanding), and lo and behold, JRE 6 is about to reach its end of support.

The new page (based on a redirect) is this Java page at the Oracle Tech Network. Later this year, the sun.com domain is supposed to go dark.

The world turns, and Java is now managed by Oracle, which bought Sun.

So, to run a Java application someone else provides, you need JRE to develop a Java application, you need JDK.Īs Chris Marasti-Georg pointed out in a comment, you can find out lots of information at Sun's Java web site, and in particular from the Java SE section, (2nd option, Java SE Development Kit (JDK) 6 Update 10). The JDK includes the compiler and other tools needed to develop Java applications JRE does not. SE defines a set of capabilities and functionalities there are more complex editions (Enterprise Edition – EE) and simpler ones (Micro Edition – ME – for mobile environments).
