![]() Then they decided to call 1.2 "Java 2" and that label lasted until Java 1.4. Sun's numbering for Java changed midstream and is a bit confusing. What is java 1.5 and 1.6? and how does that correspond to the java number (Java SE.)? Java SE 7 refers to both the JDK and the JRE.ĭoes this mean that the java JDK is the same as the java number (Java SE 7)? When you download Java you can either get the JRE (Java Runtime Environment) which only lets you run already compiled Java applications or you can get the JDK which allows you to compile and run Java apps. Is Java SE 7 also Java JDK 7? and also what is the JDK? Java EE is a set of libraries and interfaces, such as EJB, JMS, JNDI, Servlets/JSPs that are built on top of the Java SE. Java ME is intended for mobile and small devices. Java ME has its own versions as well - it is currently at version 3. There are separate edition numbers for Java EE which is up to version 6 now. "Java N" where N is some number refers to the SE. There are a couple of Java "editions", namely Java SE, the "Standard Edition", Java EE, the "Enterprise Edition" and Java ME, the "micro edition". Is Java 7 just Java SE 7? and Java 6 is Java SE 6? Also, Java 1.2 was Java 2, but everyone I know who was not working in Sun at that time always called it 1.2. Actually, after Java 1.4 they created the JCP, to involve the community in the development of Java itself, and starting from Java 1.5 it is officially named "Java 5", despite most in the industry calling it 1.5. Regarding numbering, they messed it up quite a bit. It is used to develop server side stuff, so it includes a lot of libraries used on server side. JavaME: is the mobile edition, it is what small games on old phones was made with, but it's basically a "smaller" version of Java suitable for very low capacity processors. ![]()
