whichjdk.com – Which version of JDK should I use?

To build and run Java applications, a Java Compiler, Java Runtime Libraries, and a Virtual Machine are required that implement the Java Platform, Standard Edition (“Java SE”) specification.

The OpenJDK is the open source reference implementation of the Java SE Specification, but it is only the source code. Binary distributions are provided by different vendors for a number of supported platforms. These distributions differ in licenses, commercial support, supported platforms, and update frequency.
