How to Install JDK on Mac OS X Step 1: Check if JDK has been Pre-Installed. In some Mac systems (earlier than Mac OS X 10.7), JDK has been pre-installed. To check if JDK has been installed, open a 'Terminal' (Search 'Terminal'; or Finder ⇒ Go ⇒ Utilities ⇒ Terminal) and issue this command: javac -version. Java SE Development Kit 8 Downloads. Thank you for downloading this release of the Java™ Platform, Standard Edition Development Kit (JDK™). The JDK is a development environment for building applications, applets, and components using the Java programming language. Basically I previously had written an article how to install Java SE 7 / JDK 7 on Mac OS X Lion. I just would like to rewrite on the newest version. Download Oracle JDK 8 from Oracle website.

  • Administrator privileges.

Note that installing the JDK on a Mac is performed on a system wide basis, for all users, and administrator privileges are required. You cannot install Java for a single user.

Installing the JDK also installs the JRE. The one exception is that the system will not replace the current JRE with a lower version. To install a lower version of the JRE, first uninstall the current version.

JDK 7 Installation Instructions

Installation of the 64-bit JDK on Mac Platforms

When you download the Java Development Kit (JDK), the associated Java Runtime Environment (JRE) is installed at the same time. The JavaFX SDK and Runtime are also installed and integrated into the standard JDK directory structure.

Depending on your processor, the downloaded file has one of the following names:

  • jdk-7u<version>-macosx-amd64.dmg
  • jdk-7u<version>-macosx-x64.dmg

Where <version> is 6 or later.

1. Download the file. Before the file can be downloaded, you must accept the license agreement.

2. From either the Downloads window of the browser, or from the file browser, double click the .dmg file to launch it.

3. A Finder window appears containing an icon of an open box and the name of the .pkg file Double click the package icon to launch the Install app.

4. The Install app displays the Introduction window. Click Continue.

4a. Note that, in some cases, a Destination Select window appears. This is a bug, as there is only one option available. If you see this window, select Install for all users of this computer to enable the continue button. Click Continue.

5. The Installation Type window appears. Click Install.

6. A window appears which says 'Installer is trying to install new software. Type your password to allow this.' Enter the Administrator login and password and click Install Software.

7. The software is installed and a confirmation window appears. Click the ReadMe for more information about the installation.

After the software is installed, delete the dmg file if you want to save disk space.

Determining the Default Version of the JDK

A: If you have not yet installed Apple's Java Mac OS X 2012-006 update, then you are still using a version of Apple Java 6 that includes the plug-in and the Java Preferences app. See Note for Users of Macs that Include Apple Java 6 Plug-in.

There can be multiple JDKs installed on a system – as many as you wish.

When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.

You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 7u6, you will see a string that includes the text 1.7.0_06. For example:

To run a different version of Java, either specify the full path, or use the java_home tool:

For more information, see the java_home(1) man page.

Uninstalling the JDK

To uninstall the JDK, you must have Administrator privileges and execute the remove command either as root or by using the sudo(8) tool.

Navigate to /Library/Java/JavaVirtualMachines and remove the directory whose name matches the following format:*

For example, to uninstall 7u6:

Do not attempt to uninstall Java by removing the Java tools from /usr/bin. This directory is part of the system software and any changes will be reset by Apple the next time you perform an update of the OS.

*The 7u4 and 7u5 releases were installed into a directory that does not follow this format. To uninstall 7u4 or 7u5, remove the 1.7.0.jdk directory from the same location.

Java is open-source, fortunately. Accessing its source code is, unfortunately, not so intuitive on Mac OS X Lion when using Eclipse. This article will guide you through the steps required to be able to view Java’s source code in Eclipse.

  • 2Downloading the JDK
  • 3Using the JDK in Eclipse

Determine your Java version ∞

Apple uses a different versioning system for Java than Oracle. For example, on my system the actual Java version is “1.6.0_29” (determined by calling java -version from a terminal), but this version comes as “Java for Mac OS X 10.7 Update 1” through Apple’s Software Update.

To find out which Java Update you’re running, go to the System Preferences and click Software Update.

Then you click on Installed Software and search the list for the latest Java update (here “Update 1”).

That’s the “Java version” you need to know.

Downloading the JDK ∞

When working with Java, you need to distinguish two Java software package types:

  • JRE: The “Java Runtime Environment” is necessary to run Java application. You cannot, however, compile Java programs with just the JRE.

  • JDK: The “Java Development Kit” is required when you want to compile Java programs. The JDK includes the JRE, and also comes with Java’s source code.

Remark: Eclipse comes with its own Java compiler. That’s why you don’t need to install a JDK to create Java programs with Eclipse. Eclipse doesn’t ship with the Java source code though. That’s why we still need the JDK.

The JDK for Mac OS X comes as “Java Developer Package”. You can download it here:

You’ll need an AppleID to download the JDK. Fortunately, it’s free but you still need to register it. (Tip: You can use the same you use in the iTunes Store.) After logging in, type “java developer package” in the search field (see screenshot).

Make sure the you download the Java Developer Package matching your Java version. In my case, this is “Mac OS X 10.7 Update 1”.

Note: Don’t confuse “10.7” for Java 7. It’s still Java 6. (So don’t download a “10.6” version when you’re running Mac OS X Lion.)

Then install the JDK. This will install the JDK under:

Note: There’s also the directory /System/Library/Frameworks/JavaVM.framework/. However, this directory seems to be deprecated.

The Java source code will be located here:

Check an already installed JDK ∞

To check whether you’ve already installed a JDK, check the list of installed updates (see above) for an entry called “Java Developer Package”.

Note: Unfortunately, the Java Developer Package listed in the list doesn’t have any (visible) version information attached to it. I’m not sure whether the JDK will be updated automatically when a new version becomes available.

To check the actual Java version of the installed JDK, go to /Library/Java/JavaVirtualMachines/ and check whether a package called like “1.6.0_29-b11-402.jdk” can be found there. In this example, the Java version would be “1.6.0_29”.

Using the JDK in Eclipse ∞

On Mac OS X, Eclipse provides an automatic way to determine the directory of the installed JDK. Go to the Eclipse Settings and open Java –>Installed JREs.

Then, by clicking on the Search.. button, would find the newly installed JDK. Unfortunately, there seems to be a bug in Eclipse Ingido (3.7 – and probably in earlier versions, too) that prevents this button from working correctly. Clicking on it doesn’t do anything when there’s already one (and only one) JRE listed here; see screenshot.

To fix this problem, do the following:

  1. Duplicate the existing entry (by hitting the Duplicate.. button)
  2. Delete the original entry; it’s the one with checked checkbox in front of it.
  3. Then click Search... This should add two new entries to the list (see next screenshot).
  4. Delete the entry you’ve created in step 1 (i.e. the duplicate of the original entry).
  5. Check one of the remaining entries. Note: The new two entries are linked. If you check one, both will be checked. Also, you can’t delete the entry for /System/Library/Java/... Trying to do so will delete the other entry.
  6. Close the Settings dialog with OK.

  7. Restart Eclipse. This will remove the wrong entry (the one for /System/Library/Java/..) from the list.

The list of installed JREs then should look like this:

Manually adding a JDK ∞

Free Software For Mac

If you want (for any reason) to add the JDK manually, here’s how to do this:

  1. Go to Installed JREs in the Eclipse Settings.
  2. Click Add..
  3. Choose “MacOS X VM” and hit Next..
  4. Specify /Library/Java/JavaVirtualMachines/<javaversion>.jdk/Contents/Home/ under JRE Home. Note: You need to type/paste the directory directly into the field. You can’t use the Directory.. as the directories in the JavaVirtualMachines directory are so called “Mac OS X packages”. These directories are displayed as files and you can’t browse their contents from within the dialog.

  5. Give the JDK a meaningful name and hit Finish.
