Java Is Robust and Secureīeing an open-source project, OpenJDK’s code is available for anyone who wants to check or enhance its security.

New ways to program that implement new technologies, like pattern matching for the switch and Vector API, are being constantly implemented. The Java Language Specification is the set of rules that ensures that all the innovations follow the same logic and are created in accordance with Java ideology.Īll the APIs are created to be compatible with each other and Java specifications, so it has everything you need to not only write your code effectively but inspect and utilize other people’s work. And yet, at the time of its conception, it was much more organized than its competitors. These days, Java syntax is not the easiest anymore… at least for now, as there are many new features in the works that make the code easier to read and write. Java Is Simple, Object-Oriented, and Familiar The only thing you need to do is to utilize the virtual machine for the chosen platform. So if you ever wanted to play Tetris (or rule the world) using your modern microwave’s touch screen 一 Java is the easiest language to do it!īut in all seriousness, this approach, called “Write Once, Run Anywhere”, allows you to not have to deal with different architectures, OSes, drivers, or hardware. This approach allows running the same code on completely different platforms with little to no rewriting! That’s right, you can write the program once, then execute it anywhere, if you follow the guidelines. The JVM in turn uses a dynamic compiler that compiles code during the execution of the app. Java compiler works differently, it creates the special “java bytecode”, that can be executed by Java Virtual Machine running on any system. Usually, most programming languages compile their code into machine code, which is different for any platform. This is made possible by utilizing the most important feature of Java 一 JVM, Java Virtual Machine, runtime used for executing applications. Java code is architecture-neutral, meaning that if written right, it can be launched on any device, from PC to modern microwave. Java Is Architecture-Neutral and JVM Is Portable Java is able to execute with high performance.Īnd these principles are still what makes OpenJDK popular, so it is important to explore each of them and see how they affect the life of developers and end-users.Java language is architecture-neutral, and JVM is portable.Java is simple, object-oriented, and familiar.There were several goals formed at the inception of Java, including: How OpenJDK Works and What Are the Advantages There are many distributions of OpenJDK available, including Liberica JDK built by BellSoft, which is also freely available for anyone to explore and use in accordance with the open-source approach. Right now, OpenJDK’s code is available to anyone and is developed by a large community situated around Oracle. During the period from 20, more and more code was being opened. In 2006 Sun released the Java HotSpot virtual machine and compiler as free software under the GNU General Public License, and since then the history of OpenJDK started with Java 6 and 7 being open source. It first became available for download in 1994, with its first public release in 1995, and almost immediately received support in the then-popular Netscape web browser. The prototype of the language was initially named “Oak”, and was later renamed Java. The history of Java began in 1991 when engineers at Sun Microsystems became frustrated with the C and C++ programming languages’ restrictions and APIs.

What Makes Java and OpenJDK Special? How OpenJDK Came To Be In this article, we will try to answer this question, dive deep into the process of constant upgrading of OpenJDK, talk about the open-source approach to development, and describe all the things that make Java so unique. And yet it is still one of the most popular development tools in the world! How could this happen? By all means, OpenJDK should have been replaced many times already. And OpenJDK, the most popular instance of Java, is 14 years old already.

It is not a new language by any standards, especially in the industry where new solutions appear every few years and are usually better than their predecessors. OpenJDK is the development kit for Java, the language with 26 years of history behind it.
