They are not updated with the latest security patches and are not recommended for use in production.

WARNING: These older versions of the JRE and JDK are provided to help developers debug issues in older systems. The JDK includes tools useful for developing and testing programs written in the Java programming language and running on the Java TM platform. The JDK is a development environment for building applications using the Java programming language.

Then Java 5 was called both 1.5 and 5.0 and that has continued - Java 7 is also Java 1.7, Java 6 is also Java 1.6, etc.Java SE 8 Archive Downloads (JDK 8u202 and earlier) 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.

JavaSE: is the standard edition, it is usually a good fit for client side software, normal applications, etc.

Basically, since the Java ecosystem is huge, Sun decided to offer Java in different editions: When talking about JavaSE, JavaEE, JavaME etc. If you want to seriously develop Java applications, you need the JDK. It also usually contains documentation for the standard library and also all the sources of the standard library, because they are useful for developers to read and inspect. jar files, many tools for "decompiling" class files, inspect. That includes the compiler obviously (which is also contained in the JRE for some good reason, but you can ignore this fact now), the JAR utility to create. It contains the JRE as well as a lot of other useful stuff for developing Java applications. If you are running any Java program on your computer, you have a JRE installed. all the way to 1.7, also known as Java 7) usually contain improvements to both the JVM and the standard library, so the two usually need to run together, and are packaged together in the JRE. It contains all the stuff in java.* packages and some private stuff in com.sun, com.oracle packages.ĭifferent versions of Java (1.0, 1.1, etc. The standard library is itself very important, because it contains a lot of useful things you'll use when developing Java applications. It includes everything needed to run a Java application, that is the JVM itself, the standard library and a bunch of other files. However, commonly a sysadmin will say "the JVM" to indicate the actual binary running on the server). (many will disagree and say that the JVM is only one, and it's a specification.

but there are also many alternative JVMs, JVMs for embedded device etc. There are many JVMs, for example you need a JVM for Windows, one for Linux, one for OSX etc. class files packaged together) and execute it.
