This article shows you how to install Java on Mac OSX, and also how to do Java/JDK version switching.

The recent Java Mac OS X 2012-006 update from Apple removes the Apple Java 6 plug-in from your Mac. The Mac OS X Install FAQ will be updated with the next 7u release, but you may find the following information useful in the meantime. See 'Note for Users of OS X that Include Apple Java 6 Plug-in'. Only one JRE can be installed. Installing a JRE removes the previously installed JRE. The JRE version used by the system can be determined in one of two ways: From System Preferences click the Java icon from the Other category. This launches the Java Control Panel.

Oracle java free download - Oracle Java, Oracle Berkeley DB Java Edition, Java Runtime Environment (JRE), and many more programs. Official Java runtime for Mac OS X Lion or higher. Oracle 10g free download - Oracle 10g, OpenLink Lite Edition ODBC Driver for Oracle 10g, Adobe Flash Player, and many more programs. Official Java runtime for Mac OS X Lion or higher. Download Java 15. Java SE 15.0.1 is the latest release of Java SE Platform. Oracle strongly recommends that all Java SE users upgrade to this release.

Tested with

  • Mac OS 10.15.3
  • JDK 8, 9, 10, 11, 12, 13 (AdoptOpenJDK)

Note
On Mac OSX, Java should installed in this folder; it is Mac’s standard.

We will show you two ways to install Java JDK on Mac, via the popular Homebrew package manager and manually installation.

1. Homebrew

1.1 Install Homebrew and update it.

1.2 Add adoptopenjdk/openjdk.

1.3 Find all available JDK.

The output may vary.

1.4 Java 8, 9, 10, 11, 12, 13, choose one to install.

This example will install Java 8 and 11 for testing.

1.5 Where Java is installed? /usr/libexec/java_home -V

Homebrew will install the JDK at folder /Library/Java/JavaVirtualMachines/, and this folder is Mac’s standard folder for Java installs.

1.6 Test it, by default, Mac takes the highest version.

1.7 How to do version switching? Refer to below 3. version switching

2. Manual installation

The example shows you how to download the early access JDK 14 and install it on Mac OSX.

Steps

Oracle java 1.8 download for mac
  • Download JDK.
  • Puts the JDK folder at /Library/Java/JavaVirtualMachines.
  • Export JAVA_HOME.

2.1 Download the early access JDK 14 from the OpenJDK website.

2.2 Extracts tar file to /Library/Java/JavaVirtualMachines

2.3 Export JAVA_HOME.

Find out where is JDK 14.

Create or edit the existing ~/.bash_profile with a text editor.

Export JAVA_HOME, save and exit.

~/.bash_profile

Reflect the changes

2.4 Test it.

3. Version Switching

In this tutorial, we installed the Java 8 and Java 11 via Homebrew (Step 1), and Java 14 manually (Step 2), so this Mac has three versions now. And the Mac is using the JDK 14.

Note
There are tools like jEnv to manage the Java version switching, but I prefer to manage with export JAVA_HOME manually, it’s simple and easy to understand, no black box magic.

3.1 Create or edit the existing ~/.bash_profile with a text editor like vim or nano, export JAVA_HOME to the specified JDK we want to use on Mac.

The above changes will make JAVA_HOME point to JAVA 8.

3.2 Reflect the changes.

Done.

If we want to switch JDK version again, update the ~/.bash_profile and export JAVA_HOME to other JDK version.

The following are the system requirements for installing the JDK and the JRE on macOS:

Java For Mac Os

  • Any Intel-based computer running macOS.

  • Administrator privileges.

    You cannot install Java for a single user. Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK and JRE on macOS.

  • When you install the JDK, it also installs the JRE. However, the system will not replace the current JRE with a lower version.

    To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.

  • When you install the JRE, you can install only one JRE on your system at a time. The system will not install a JRE that has an earlier version than the current version.

    To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.

    Note:

    Installing a JRE from Oracle will not update java -version symlinks or add java to your path. To do this, you must install the JDK.
