Download Jdk 7 For Mac
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. How to install Java JDK Java Development Kit on mac. In Mac OSX 10.5 or later, Apple recommends to set the $JAVAHOME variable to /usr/libexec/javahome, jus. I think that's how I've usually done it on Windows, though I haven't ever switched off the default JDK on my Mac. If that doesn't work, you could try installing a different distribution of JDK 7 - there were a few different ones available at the openjdk-osx-build site, maybe you.

System Requirements
Observe the following requirements:

Note that installing the JDK on OS X 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 as described in 'Uninstalling the JRE'.

Depending on your processor, the downloaded file has one of the following names:
jdk-8u
version
-macosx-amd64.dmg
jdk-8u

Determining the Default Version of the JDK
If you have not yet installed Apple's Java 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 OS X 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 8u6, you will see a string that includes the text 1.8.0_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.
