Response to the parent: how exactly is “Apple is heavily dependent on Java in OS X” ? To my knowledge, there is no part of OSX that uses Java, not the kernel, not the desktop, not any delivered utilities. So Apple is evil for first not continuing their own slightly bespoke version of Java, and now apple is evil for contributing code to OpenJDK, and encouraging a more “standard” Java for OSX? I’m not prone to black helicopter thinking, but this smells incredibly fishy to me. So, Apple joins OpenJDK, contributes a boatload of code and commits to Java on Mac OS X not long after Oracle sues Google over Android. Combined with last month’s announcement of IBM joining the OpenJDK, the project now has the backing of three of the biggest names in software.” The Java developer community can rest assured that the leading edge Java environment will continue to be available on Mac OS X in the future. “We are excited to welcome Apple as a significant contributor in the growing OpenJDK community,” said Hasan Rizvi, senior vice president of development at Oracle, “The availability of Java on Mac OS X plays a key role in the cross-platform promise of the Java platform. The OpenJDK community will then be able to access and contribute to the project. Apple will supply key components for a Java SE 7 implementation on Mac OS X, including a 32bit and 64bit HotSpot-based Java virtual machine, class libraries, a networking stack, and the foundation for a new graphical client. Why do I have this image in my head?Īpple has always developed its own version of Java for Mac OS X, but the company is now handing over development to the OpenJDK project. Well, we now know why: Apple and Oracle have announced that Apple will contribute to the OpenJDK project, effectively meaning that Java for Mac OS X will be developed by the OpenJDK community. Apple recently marked its Java implementation as deprecated. Side note, you can also run directly the program, without the separate compilation step with: 1 java HelloWorld.javaīut this is usually slower than compiling the code with javac and running the compiled code.Ĭategories C# Charts C++11 Regex Scheme Multithreading Posix Books C++ C++14 C++17 OSX Python Objective-C Windows Clang Fortran CUDA Roguelike Perlin Cling C++20 Linux WSL Fractals OpenGL JavaScript OpenCV BeagleBone Productivity Raspberry Pi OpenMP iOS Node.The jokes about two evils joining up are easily made, but I’ll try to refrain. This is what I see on my machine: 1 % javac HelloWorld.java If you want to run the compiled version: 1 java HelloWorld Save the above as HelloWorld.java and compile it with: 1 javac HelloWorld.java Just to be sure that everything works, try to compile and run a simple program: 1 class HelloWorld Now, check if you’ve successfully installed the JDK with: 1 java -version 2 javac -versionĢ openjdk version "13" 3 OpenJDK Runtime Environment (build 13+33) 4 OpenJDK 64-Bit Server VM (build 13+33, mixed mode, sharing) 5 % javac -version Next step, is to move the extracted folder to a place where macOS searches for Java JDK: 1 sudo mv jdk-13.jdk /Library/Java/JavaVirtualMachines/ Extract the archive by double clicking on the file or, assuming it is in your Downloads folder, write this in your Terminal: 1 cd ~/Downloads 2 tar xf openjdk-13_osx-圆4_ Start by getting OpenJDK, chose the macOS version. ![]() If you prefer to use the Java version provided by the OpenJDK website, you will need to use Java 13. ![]() This is what I see on my machine: 1 % java -versionĢ openjdk version "11.0.4" 3 OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.4+11) 4 OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.4+11, mixed mode) 5 % javac -version From the AdoptOpenJDK page you will download a pkg file that you can install on your macOS machine directly by double clicking on it.Īfter you’ve installed the AdoptOpenJDK pkg file, check if you can use it with: 1 java -version 2 javac -version If you still need to use Java 11, use an alternative build like the one from AdoptOpenJDK. You can still get the archived version, but this is not recommended because it doesn’t include any new security patches. At this time, Java 11, the long term release or LTS, of Java is no longer supported on the OpenJDK website.
