Oracle JDK vs. OpenJDK: Which One Should You Choose in 2026?
Oracle JDK vs. OpenJDK: What's the Difference? (Understand Your Java Development Kit Options!)
Are you wondering about the distinctions between Oracle JDK and OpenJDK? While there are many implementations of Java Development Kits (JDKs),
Oracle JDK and OpenJDK stand out as the two most prominent choices. This video dives deep into their key differences, helping you make an informed decision for your Java development needs!
What you'll learn in this video:
• Core Definitions: Understand that Oracle JDK is a proprietary implementation of Java, while OpenJDK is its open-source counterpart.
• Licensing: Discover that both Oracle JDK and OpenJDK binaries are free to use for both commercial and non-commercial purposes. Oracle JDK is released under the Oracle No-Fee Terms and Conditions License, whereas OpenJDK is distributed under the GNU General Public License version 2, with the Classpath Exception (GPLv2wCP).
• Distribution & Installation:
◦ Oracle JDK is the default Java distribution for Solaris, Windows, AIX, and macOS. It offers convenient "installers" (like .msi, .rpm, .deb) that automate update rules, common configurations such as setting JAVA_HOME in Windows, and establishing file associations (e.g., launching .jar files).
◦ OpenJDK is the default Java distribution for Linux Ubuntu, Fedora, Red Hat Enterprise Linux (RHEL), and OpenSUSE distributions. It is typically provided as a compressed archive (like .tar.gz or .zip), requiring users to manually perform common configuration tasks and set file associations.
• Feature Differences:
◦ FreeType Distribution: Oracle JDK distributes FreeType with a FreeType license, while OpenJDK distributes it with a GPLv2 license.
◦ Usage Logging: Oracle JDK supports usage logging features, which are not available in OpenJDK.
• Modern Convergence: Learn that Oracle is actively working to keep both OpenJDK and Oracle JDK binaries as close as possible. With Java 17, there are now only a few key differences between them.
Which one should you choose? Both distributions allow you to try out the latest features of Java 17. If you prefer an installer that handles post-install configurations automatically, Oracle JDK can be a preferred option. If you're comfortable with manual post-install configuration, OpenJDK is a good choice.
