System Requirements
- Any Intel-based Mac running Mac OS X 10.7.3 (Lion) or later.
- 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.

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.

file. You must login using an Oracle account (if you don’t have an Oracle account, then creating one is free).I recommend you to verity the integrity of the downloaded by comparing SHA256 checksum of the file against the value published here. On Windows, type the following command:certutil -hashfile jdk-8u251-windows-x64.exe sha256
If the generated SHA256 checksum value matches the one posted by Oracle, you’re safe to launch JDK 8 setup program. You will see this screen:Click Next twice to proceed the installation of Java 8. Then it also asks you to install JRE 8:Click Next to proceed and click Close when the setup done.
