Differences between Oracle JDK and OpenJDK
The Oracle JDK (Java Development Kit) and the OpenJDK are two implementations of the Java SE (Standard Edition) platform. Both implementations include the Java runtime environment (JRE) and the Java development tools, but there are some differences between them:
License: The Oracle JDK is proprietary software that is licensed under the Oracle Binary Code License. The OpenJDK is open source software that is licensed under the GPL (GNU General Public License) with a linking exception.
Support: Oracle provides commercial support for the Oracle JDK, including bug fixes, security updates, and long-term support releases. The OpenJDK is supported by a community of developers, and bug fixes and security updates are provided on a best-effort basis.
Features: The Oracle JDK includes additional features and tools that are not available in the OpenJDK, such as the Oracle JRockit JVM (Java Virtual Machine) and the Oracle Java Mission Control performance profiling tool.
Compatibility: The Oracle JDK and the OpenJDK are generally compatible with each other, but there may be minor differences in the implementation of certain features. If you encounter compatibility issues, you may need to use a specific JDK implementation or version.
In general, you can use either the Oracle JDK or the OpenJDK for Java development, depending on your needs and preferences. If you require commercial support or need access to proprietary features, you may prefer the Oracle JDK. If you prefer open source software or do not need commercial support, you may prefer the OpenJDK.
