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.
