This article shows you how to install Oracle JDK $java_version on your
Mac system. This article uses JDK $java_version$java_update_no to
demonstrate the installation. In the provided commands, replace the
version specific paths and file names according to the downloaded
version.
Oracle provides a Mac installer and a binary file.This article
explains how to install Oracle JDK using the mac installer and how to
set the JAVA_HOME variable.
Step 1:
Download the macOS installer(jdk-$java_version$java_update_no_osx-x64_bin.dmg) from this
official site:
Step 2:
Step 4:
After installing Java, close the installation wizard, open the terminal and enter the following two commands to check the installed java and javac version.
If you see the installed Java version for both of these commands, you have successfully installed the Oracle JDK.
Step 2:
Double-click the
jdk-$java_version$java_update_no_osx-x64_bin.dmg file. You will
see a finder window with the JDK $java_version$java_update_no.pkg file. Double-click the JDK $java_version$java_update_no.pkg file to
start the installer.
Step 3:
Click "Continue" and follow the installation wizard to install Oracle
JDK.
After installing Java, close the installation wizard, open the terminal and enter the following two commands to check the installed java and javac version.
java -version
javac -versionIf you see the installed Java version for both of these commands, you have successfully installed the Oracle JDK.
Step 5:
Some software like Apache Maven requires the
JAVA_HOME path to find the
active Java path. Based on the Terminal Shell, the
JAVA_HOME path must be
declared either in the
~/.bash_profile or the
~/.zshenv file.
Step 5.1:
Enter the following command to get the installed Java locations. If
you have more than one Java installations, you will see all of them
listed in the output.
/usr/libexec/java_homeYou may get an output similar to this:
/Library/Java/JavaVirtualMachines/jdk-$java_version$java_update_no.jdk/Contents/HomeIn case if you have multiple Java installations, all their installation folders will be listed here. Pick the one you want to set as the default Java Home.
Step 5.2:
Enter the following command to check the Shell type.
echo $SHELL
If you are running macOS Catalina or latest, you will get
/bin/zsh
as the shell type. Older Mac versions use
/bin/bash
as the default shell.
Step 5.3:
If the default shell is "bash", enter the following command to edit the
".bash_profile" file.
nano ~/.bash_profile
If the default shell is "zsh", use the following command to edit the
".zshenv" file.
nano ~/.zshenv
nano is used here to open the profile file. You can use your favorite
editor instead of nano.
Step 5.4:
In the opened file, add the following line to define JAVA_HOME.
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-$java_version$java_update_no.jdk/Contents/Home
Save the changes and close
nano
(Ctrl + O, Ctrl + X).
Step 6:
Enter the following commands to test if the JAVA_HOME is properly set.
Run the following command if your shell is bash:
source ~/.bash_profile
echo $JAVA_HOMEsource ~/.zshenv
echo $JAVA_HOMEStep 9:
Restart the computer to avoid running source command every time you open the terminal.
