To see all the installed java: $ jenv versionsĪbove command will give the list of installed java: * system (set by /Users/lyncean/.jenv/version)Ĭonfigure the java version which you want to use: $ jenv global oracle64-1.6.0.39 $ jenv add /Library/Java/JavaVirtualMachines/jdk1.11.0_2.jdk/Contents/Home $ echo 'eval "$(jenv init -)"' > ~/.bash_profileĪdd the installed java to jenv: $ jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_202.jdk/Contents/Home $ echo 'export PATH="$HOME/.jenv/bin:$PATH"' > ~/.bash_profile Install and configure jenv: $ brew install jenv If you want to install/manage multiple version then you can use 'jenv': To install java 8: $ brew cask install adoptopenjdk/openjdk/adoptopenjdk8 To install latest java: $ brew cask install java
Install cask (with Homebrew 0.9.5 or higher, cask is included so skip this step): $ brew tap caskroom/cask Why doesn't Oracle's installer put it where it really goes? And how can I work around this problem?Īssumption: Mac machine and you already have installed homebrew. Ironically, the "Java" control panel under System Preferences shows only Java 1.8! usr/libexec/java_home -V still only lists the old Java 1.6. I've tried adding a symbolic link to make it look like 1.8 is in the /System/Library. But /usr/libexec/java_home doesn't find 1.8, so all the posts I've found on how to set your current java version don't work. Not sure why the latest installer puts this in /Library instead of /System/Library (nor what the difference is). I ran Oracle's Java 8 installer, and the files look like they ended up at /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdkīut previous versions are at /System/Library/Java/JavaFrameworks/jdk1.6. I'm using IntelliJ 13 CE and Mac OS X 9 Mavericks. I want to do some programming with the latest JavaFX, which requires Java 8. Make sure that the class name and file name are the same.Editors note: This question was asked in 2014, and the answers may be outdated. Now write the first Java program as shown below, save the program as HelloWorld.java and exit the editor. In this step, we will write, compile, and execute our first program in Java using the standard Hello World example. You can follow How To Switch Java Version On Mac. It might be required to switch the active Java in case multiple JDKs are installed on the same Mac machine. This is all about installing Oracle JDK 17 on Mac systems including macOS Sierra, High Sierra, Mojave, Catalina, and Big Sur.
