Update: yes, all of the above is still correct after Oracle bought Sun and Java 7 (specified in JSR 336) was released. So if you're told to install "Java 1.6" for a software development course, then the JDK 6 is definitely the correct piece of software to install. "Java 1.6" doesn't exist, strictly speaking, but is usually written to refer to Java SE 6."JDK 1.6" doesn't exist, strictly speaking, but is usually written to refer to JDK 6.
"Java SE 6" is the "Java Standard Edition 6 platform", which is a specification of what the platform looks like.The Java platform itself is simple "Java SE 6" (no "1." anywhere to see). But that's only the internal version number of that piece of software. It's an implementation of the Java SE 6 platform as specified by JSR 270 together with a set of development tools (the implementation of the platform without the development tools is called the JRE: Java Runtime Environment).įor some reason the internal version number of the JDK 6 is "1.6" (or 1.6.0_17 for example).
