Oracle JDK vs OpenJDK 8: What's the Difference?

As a Java developer, understanding the difference between Oracle JDK, OpenJDK, and other related terms is crucial for navigating the Java ecosystem with ease. In this article, we'll explore the differences between Oracle JDK and OpenJDK 8, and help you make an informed decision about which one to use.

Oracle JDK (Java Development Kit) is a software development kit that is used to develop Java applications. It includes the JRE (Java Runtime Environment), as well as a number of tools and libraries specifically designed for Java development. This includes the Java compiler, which is used to turn your Java code into executable programs, as well as other tools such as debuggers, profilers, and more.

On the other hand, OpenJDK is an open-source version of the JDK. It includes the same tools and libraries as the JDK, but it is freely available and can be modified and redistributed by anyone. OpenJDK is a popular choice for developers who want a free and open-source alternative to the JDK.

One of the key differences between Oracle JDK and OpenJDK 8 is the licensing terms. Oracle JDK is licensed under the Oracle Technology Network (OTN) license, which requires users to accept certain restrictions on usage and redistribution. OpenJDK, on the other hand, is licensed under the GNU General Public License (GPL), which allows for free use, modification, and redistribution.

Another difference is the level of support provided by Oracle. Oracle JDK comes with official support from Oracle, including bug fixes, security updates, and documentation. OpenJDK, while supported by a community-driven project, does not come with official support from Oracle.

In terms of functionality, both Oracle JDK and OpenJDK 8 provide similar tools and libraries for Java development. However, OpenJDK may have some limitations compared to Oracle JDK, such as missing certain features or functionalities.

In conclusion, while both Oracle JDK and OpenJDK 8 are viable options for Java development, the choice between the two ultimately depends on your specific needs and requirements. If you need official support from Oracle and are willing to accept the licensing terms, then Oracle JDK may be the better choice for you. However, if you're looking for a free and open-source alternative that can be modified and redistributed, then OpenJDK 8 is definitely worth considering.
