We should note that before this long-running project, there were JDK Release Projects that released one feature and were then discontinued. Be sure to include complete version information from the output of the java -version command. Feedback If you have suggestions or encounter bugs, please submit them using the usual Java SE bug-reporting channel. And, just like for Oracle, the JDK Project will also deliver new feature releases every six months. API Javadoc Builds Notes If you have difficulty downloading any of these files please contact. Initially, it was based only on the JDK 7, but since Java 10, the open-source reference implementation of the Java SE platform is the responsibility of the JDK Project. OracleJDK is no longer free for commercial use, but OpenJDK is still free. We should emphasize that OpenJDK is an official reference implementation of a Java Standard Edition since version SE 7. Note: the versions in italics are no longer supported. Let's take a look at the Java SE history: Nowadays there are many JRE packages available from a variety of projects and companies, but the two most popular on Ubuntu are OpenJDK and Oracle HotSpot.

Oracle strongly recommends using the term JDK to refer to the Java SE (Standard Edition) Development Kit (there are also Enterprise Edition and Micro Edition platforms). It's thus named because it contains more tools than the standalone JRE, as well as the other components needed for developing Java applications. To verify these packages, download our public keys and follow the instructions on how to verify IBM Semeru Runtimes. It contains a complete Java Runtime Environment, a so-called private runtime.

JDK (Java Development Kit) is a software development environment used in Java platform programming.
