How to install a specific JDK on Mac OS X

Question

I want to install a specific JDK  the latest for example   For this  I went to the JDK download homepage  http   java sun com javase downloads index jsp  I looked for a Mac version  but I m a bit surprised to only see downloadable versions for Linux  Windows and Solaris     Here s the message for Mac       Apple Computer supplies their own version of Java  Use the Software   Update feature  available on the Apple menu  to check that you have   the most up-to-date version of Java for your Mac     OK BUT    when I update Java with Mac I have a JRE and not a JDK     I don t understand why a JDK version doesn t exist that is easily downloadable installable  like a jar to unzip   for Mac

As a rule you cannot install other versions of Java on a Mac than those provided by Apple through Software Update. If you need Java 6 you must have a 64-bit Intel computer. You should always have Java 5 and 1.4 and perhaps 1.3 installed if you have at least OS X 10.4.

If you have VERY much elbow grease and is willing to work with beta software you can install the OpenJDK under OS X, but I don't think you want to go there.

Since most answers are out of date  here s what works as of end of 2018 under the assumption that   You want to install the GPL version of OpenJDK  0  You do not want to install Homebrew   In that case  grab the desired version from one the many available  freely usable OpenJDK editions  e g     AdoptOpenJDK Amazon Corretto  Great for production  includes backports  Oracle GPLv2 OpenJDK   Some of these include installers  but if not you can do the following   Assuming here version 11 0 1 for Mac  In your favorite shell  run   tar -xzf openjdk-11 0 1 osx-x64 bin tar gz sudo mv jdk-11 0 1 jdk  Library Java JavaVirtualMachines   Fix owner and group sudo chown -R root wheel  Library Java JavaVirtualMachines jdk-11 0 1 jdk    Optional  Check if the new JDK can be found  usr libexec java home   gt   Library Java JavaVirtualMachines jdk-11 0 1 jdk Contents Home    0  Note that the Oracle branded JDK has significant licensing restrictions allowing you its use basically only for testing  i e   not for production  If you do not have a support agreement with Oracle  then it seems risky to me to use their JDK  especially since the differences to OpenJDK are minimal   Edit  added more choices

I think this other Stack Overflow question could help   How to get JDK 1 5 on Mac OS X  It basically says that if you need to compile or execute a Java application with an older version of the JDK  for example 1 4 or 1 5   you can do it using the 1 6 because it is backwards compatible  To do it so you will need to add the parameter -source 1 5 and or -target 1 5 in the javac options or in your IDE

In a comment under  Thilo s answer   mobibob asked how to set JAVA HOME in your  bash profile on a Mac  Answer   export JAVA HOME   usr libexec java home     This will dynamically assign to JAVA HOME the location of the first JDK listed in the  General  tab of  Java Preferences  utility   See Apple Technical Q amp A 1170  https   developer apple com library content qa qa1170  index html  EDIT   If you prefer parentheses to backticks for command substitution  this also works   export JAVA HOME    usr libexec java home

JDK is the Java Development Kit  used to develop Java software    JRE is the Java Runtime Environment  used to run any  jar file  Java software     The JDK contains a JRE inside it   On Windows when you update Java  it updates the JRE automatically   On Mac you do not have a JRE separated you have it  but inside the JDK  so when you update Java it will update your JRE which is inside your JDK  it doesn t install an JDK for you  You need to get it from somewhere else

The explanation is that JDK is a bit specific and does not contain the library tools jar  For my development  I need this library and Mac s JDK doesn t provide it    Cf  http   developer apple com mac library documentation Java Conceptual Java14Development 02-JavaDevTools JavaDevTools html      tools jar does not exist  Classes usually located here are instead included in classes jar  Scripts that rely on the existence of tools jar need to be rewritten accordingly    It sucks

As the message says  you have to go to Apple  not Sun  for Java on the Mac  As far as I know  Apple JDK 6 is installed by default on Mac OS X 10 6  Snow Leopard   Maybe you need to install the developer tools from your Mac OS X installation DVD  the dev tools are an optional install from the OS DVD    See  http   developer apple com java   NOTE This answer from 16 Oct 2009 is now outdated  you can get the JDK for Mac OS X from the regular JDK download page on Oracle s website now

Compiling with -source 1 5 -target 1 5  in a JDK 6 environment  will honor only language elements that were in 1 5 and prior   Great   But there were no language changes in 6 anyway   Problem with this approach  on Mac with 1 6  is that using classes that came AFTER 1 5 will still compile because they exist in the rt jar   So one could run in a 1 5 env and get a class not found exception with no prior warning when compiling   I found this out the hard way with javax swing event RowSorterEvent Listener   Both entered  Since 1 6  but are not caught with -source 1 5
