We should note that before this long-running project, there were JDK Release Projects that released one feature and were then discontinued. And, just like for Oracle, the JDK Project will also deliver new feature releases every six months. The following versions: 14.0, 11.0 and 9.0 are the most frequently downloaded ones by the program users. This free PC program was developed to work on Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10 or Windows 11 and can function on 32 or 64-bit systems.
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. This free software is a product of Sun Microsystems, Inc. We should emphasize that OpenJDK is an official reference implementation of a Java Standard Edition since version SE 7.
