#JAVA VERSIONS INSTALL#

The java plugin is added, a specific version (there are versions for adoptopenjdk, corretto, dragonwell, graalvm, liberica, mandrel, microsoft, openjdk, oracle, sapmachine, semeru, temurin, trava, zulu) is installed and configured to be the global (or local version) to use: asdf plugin-add java # Add java PluginĪsdf list-all java # List all available java versionsĪsdf install java temurin-20.0.1+9 # Install specific jdk versionĪsdf install java temurin-17.0.7+7 # Install another jdk versionĪsdf global java temurin-17.0.7+7 # Set the global jdk versionĪsdf local java temurin-20.0.1+9 # Set the local version for calls from the current directoryĪsdf uses a file in $HOME/.tool-versions to configure the global selected version.

#JAVA VERSIONS HOW TO#

Here is an example how to setup a new install (you can also install completion so you don't have to list the versions first). OpenJDK 6 is an open-source implementation of the Java SE 6 Platform, it's different from Sun's JDK.As it is not (yet) in the list of possibilities, there's also asdf.Īsdf does not only provide version management for java, it has plugins for ~400 different languages and tools by default, you can find more on github, or create your own. Two Products are delivered under the platform: the JDK TM 6 and the JRE TM 6. So, to summarize, the whole naming is a mess but this is finally over and the current platform name is Java TM Platform, Standard Edition 6 (abbrev. Where you might have expected to see 1.5.0, it is now 5.0 (and where it was 1.5, it is now 5). The number '5.0' was arrived at by dropping the leading '1.' from '1.5.0'. The number '5.0' is used to better reflect the level of maturity, stability, scalability and security of the J2SE. Version '5.0' is the product version, while '1.5.0' is the developer version. The number 6 is used to reflect the evolving level of maturity, stability, scalability and security of Java SE.īoth version numbers '1.5.0' and '5.0' are used to identify this release of the Java 2 Platform Standard Edition. Version 6 is the product version, while 1.6.0 is the developer version. The official name is Java TM Platform, Standard Edition 6.īoth version numbers (1.6.0 and 6) are used to identify this release of the Java Platform.

J2SE SDK/JRE Version String Naming ConventionĪnd quoting Java SE 6 Platform Name and Version Numbers:Īt this release, the platform name has changed from J2SE TM to Java TM SE.

#JAVA VERSIONS FOR FREE#

But you can also get builds for free from AdoptOpenJDK (which recently rebranded as 'Adoptium'), they just aren't supported as long. Instead, they just provide OpenJDK builds and provide commercial long term support for them with bugfixes and security patches. In the more than 10 years since then, Java was sold to Oracle, OpenJDK became the official Java reference implementation, and Oracle stopped maintaining the Oracle JDK as a separate codebase. Note also that when this question was asked, Sun JDK and OpenJDK were separate codebases (whith a large overlap), and Sun JDK was the official reference implementation. All GA (FCS) versions are ordered based on the standard dot-notation. We now have Java 15, Java 16, Java 17, etc. The content of the system property can be expanded (beyond that of the java.version system property) to include the build id.

#JAVA VERSIONS CODE#

Starting with Java 9 or 10, the 1.X notation also disappeared from the output of java -version (which caused some code that depended on parsing it to break), and people have pretty much stopped using it.Starting with Java 6, they've dropped the minor version and mostly (but not completely, see output of java -version) eliminated the traces of the old versioning scheme, but people have gotten used to it and continue to use it colloquially.

The next version was then supposedly 'Java 5.0', but there was still '1.5' all over the place in the file names and URLs.

This continued until 1.4 (There were also minor releases like 1.4.2).

Then came Java 1.2, but you were supposed to call it 'Java 2, JDK 1.2'.
