Java is one of the most popular and used programming languages out there. There are two types of Java JDK (Java Development Kit), one is Oracle JDK and OpenJDK.
Do you know the difference between the Oracle JDK and OpenJDK? Let’s go through this article to find out the same. There are numerous differences, but currently, both of them are acquired by Oracle. So, without any further ado, let’s jump directly to the main point.

What is JDK?
JDK stands for Java Development Kit. It is a software development platform. It particularly finds its use in the development of various Java applications and applets.
There are certain components of JDK which include the Java Runtime Environment (JRE), an interpreter/loader (Java), a compiler (javac), an archiver (jar), a documentation generator (Javadoc) and other tools needed in Java development.
What is Oracle JDK?
Oracle Java JDK is acquired by the Oracle Corporation, but earlier it was developed by Sun Microsystems. It is a set of computers software and specifications which provides a system for developing various application software.
It finds its implementations in various platforms such as embedded devices, mobile phones, enterprise servers, supercomputers, etc. However, Oracle maintains both the platforms on its own.
What is OpenJDK?
OpenJDK is a free and open platform for Java. It was basically developed from an effort initiated by sun Microsystems in 2006. Oracle further sponsored it. Few components that come with the open java project are java class library, the java compiler, the java runtime environment, and the java virtual machine.
Oracle JDK vs OpenJDK
Some of the key differences between OracleJDK and OpenJDK are as follows:
1. The Releases
Open Java will deliver releases every six months, while the oracle java will be released every three years. You will get long term support with oracle for its releases. On the contrary, Open Java provides changes for any release until the launch of the next version.
2. Licenses
Oracle binary code license agreement authenticated the Oracle JDK. On the other hand, the OpenJDK possesses the GNU general public license version 2 along with a linking exception.
3. Overall output
Basically, both of the java platforms have no real technical differences as the build process for the Oracle JDK is based on that of OpenJDK. When it comes to the overall performance of the platform, then the Oracle Java is comparatively much better than the OpenJDK in terms of responsiveness and JVM performance. On the other hand, OpenJDK delivers release more often; therefore, it increases instability.
4. Specifications
The oracle java has a flight recorder, java mission control, and application class-data sharing features. Whereas, the OpenJDK possess the font renderer feature.
Benefits Over Each Other
- The releases for the OpenJDK are quite frequent as compared to the Oracle Java.
- The Oracle Java concentrates more on the stability as it gives more importance to the more of its enterprise audience; however, it is quite unstable in terms of releases.
- The Oracle Java possesses great GC options with better and improved renderers, and on the other hand, OpenJDK has lesser GC options and slower graphics.
- OpenJDK has more open source community.
Conclusion
In the above-provided information, the two most popular Java Development Kits are discussed. Some noticeable features of both the platforms are mentioned along with their benefits over each other.
