- Jan 16, 2015 If you would like to learn Java programming, the best way is by writing Java codes by yourself. To compile the Java codes then you need Java Development Kit (JDK). It can be Oracle JDK or OpenJDK. This post guides you how to install Oracle JDK 8 on Mac OS X 10.10 Yosemite.
Install HomeBrew first
If you get the error 'already installed', follow the instructions to unlink it, then install again:
NOTE: When I write java -version on terminal or command prompt, java version 1.8.0171 will return on terminal which signifies Java 8 is already there on my system. How to Install Java on Mac OS? If you do not have java on your system follow the steps below. We will download and install java on MAC OS.
Mac Install Java 1.8
upgrade brew:
brew update && brew upgrade brew-cask && brew cleanup && brew cask cleanup
Install Java 7 and 8
People on the Stackoverflow cautioned not to install 8 until 7 is installed. So we are going to install JDK 7 first.
Install Java Mac Os
Unlike other version managers such as NVM, jEnv itself doesn’t install JDKs. You have to do it yourself. Luckily, Homebrew Cask made this task really easy. But before doing that, let’s check if we already have JDK 7 installed by Homebrew Cask:
install Java 7:
brew cask install java7
If you run into permission issue, add sudo at the beginning of the above command.
As of today, Java 8 is the latest stable. Run the following command to install Java 8:
brew cask install java
These two JDKs will be installed at the following directories. Your JDKs’ minor and patch versions might be different.
Enter jEnv
Now it is time to install jEnv:
brew install jenv
Add the following lines to ~/.bash_profile. This will initialize jEnv.
jEnv doesn’t install JDKs, so we have to tell jEnv where to look for them. Type these commands to register JDKs in jEnv (replace the minor and patch versions with yours):
After that, run this command to list all registered JDKs:
jenv versions
The version with an asterisk is the active version.
In my case, I need to keep JDK 7 as my default version, so I set the global version to 1.7:
jenv global oracle64-1.7.0.79
Install Java 8 Mac Dmg Free
And in my project, I set the local JDK version to 1.8:
The above command will create a .java-version file at project root. Its content is the version I just picked for this project:
Install Java 8 Mac Dmg 1
