In this tutorial, we are going to talk about one of the trending topics that are OpenJDK. Also, we are going to see what the difference between OpenJDK vs Oracle JDK is.Īfter this tutorial, we will be clear with all the basic differences between OpenJDK and Oracle JDK in Java.Īlso, you will be understanding why most of the organizations are moving to the OpenJDK. People who know Java also know that Java is acquired by the Oracle. And one of the important news about Java is that in 2019 Oracle people announced that they would start charging for the Java SE Licence. ![]() So, this is one of the big factors and a big reason why most of the organization considering switching from Oracle JDK to OpenJDK. ![]() So, what is the biggest difference between OpenJDK vs Oracle JDK. So, Licensing is the biggest difference between in OpenJDK and OracleJDK. Open JDK is open-source Java completely and while if you see the Oracle JDK then it requires a commercial license. There are other differences as well which is related to the support and cost. So, if we are comparing in terms of Coding then there is no difference between Open JDK and Oracle JDK. Using OpenJDK and writing code in your application is the same as using Oracle JDK and writing code in the application and all it is depending upon what provider are using. So here biggest question arrives so what is the recommend one out of these two JDKs?Īnd when it comes to the pros and cons then what are the pros and cons for Open JDK and Oracle JDK. Performance OpenJDK vs Oracle JDKīased on history if we compare then we see Oracle JDK has better performance as compared to the OpenJDK.īut the performance of OpenJDK is continuously growing. It is the biggest question in everyone’s mind that can we use the OpenJDK for commercial use? And efforts and contributions of the OpenJDK team and community often outperform the OracleJDK. So, answer to this is yes you can use the OpenJDK for commercial software projects. Oracle JDK requires a paid support license from version 11 onwards. OpenJDK is good or can be a good replacement for Oracle JDK in the project. In case anyone wonders, I will try to explain the difference between Oracle JDK and Open JDK. So OpenJDK has release policy that they have a feature release every 6 months and that is supportable until the next feature release. So, in simple terms, we can say that it is a continuous stream of releases and targeted to developers. Oracle JDK mostly for those or we can say that they targeted the audience who wants and value stability in their product and software. It is based on one of the OpenJDK releases, but its main thing is that it gives long term support. Have any more questions? Leave a comment.So, its release policy till now is that Oracle JDK has releases planned every 3 years now. To sum up, Java is a programming language, the JRE is a software package that is required to run Java applications, the JDK is a software development kit that is used to develop Java applications, and OpenJDK is an open-source version of the JDK. Understanding the difference between these four terms is important for any Java developer, and will help you navigate the Java ecosystem with ease. OpenJDKįinally, there is OpenJDK. 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. Then there is the Java Development Kit (JDK). The JDK is a software development kit that is used to develop Java applications. It includes the JRE, as well as a number of tools and libraries that are 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. Next, there is the Java Runtime Environment (JRE). The JRE is a software package that is required to run Java applications. It includes the Java Virtual Machine (JVM), which is responsible for executing Java code, as well as other libraries and components that are needed to run Java programs. Javaįirst, let’s start with Java. Java is a popular programming language that is used for creating a wide variety of applications, including web and mobile apps, games, and more. It is known for being fast, reliable, and easy to learn, which is why it is widely used by developers around the world. If you’re new to the world of Java programming, you may have come across a number of different terms and acronyms that can be confusing, especially if you’re not sure what they mean or how they relate to each other. In this blog post, I’ll explain the difference between four common Java-related terms: Java, JRE, JDK, and OpenJDK.
