In a comment under @Thilo's answer, @mobibob asked how to set JAVA_HOME in your .bash_profile on a Mac. Answer:

<pre><code>export JAVA_HOME=`/usr/libexec/java_home` 
</code></pre>

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: <a href="https://developer.apple.com/library/content/qa/qa1170/_index.html" rel="nofollow noreferrer">https://developer.apple.com/library/content/qa/qa1170/_index.html</a>

EDIT:

If you prefer parentheses to backticks for command substitution, this also works:

<pre><code>export JAVA_HOME=$(/usr/libexec/java_home)
</code></pre>

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: <a href="http://developer.apple.com/java/" rel="noreferrer">http://developer.apple.com/java/</a>

blocks|key|2600216|text|的解释是，JDK有点特定，不包含库tools.jar。对于我的开发，我需要这个库，Mac的JDK没有提供它：|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|2600217|(比照http://developer.apple.com/mac/library/documentation/Java/Conceptual/Java14Development/02-JavaDevTools/JavaDevTools.html)|2600218|tools.jar不存在。通常位于这里的类被包含在classes.jar中。依赖于tools.jar存在的脚本需要相应地重写。|blockquote|2600219|真没意思!|2600220|entityMap|0|LINK|mutability|MUTABLE|url|http://developer.apple.com/mac/library/documentation/Java/Conceptual/Java14Development/02-JavaDevTools/JavaDevTools.html^0|0|Q|0|3|3C|0|0|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|X|8|@]|D|@$9|Y|A|Z|1|10]]|E|$]]|$1|H|3|I|5|J|7|11|8|@]|D|@]|E|$]]|$1|K|3|L|5|6|7|12|8|@]|D|@]|E|$]]|$1|M|3|-4|5|6|7|13|8|@]|D|@]|E|$]]]|N|$O|$5|P|Q|R|E|$S|T]]]]

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:

<blockquote>
 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.

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

Since most answers are out of date, here's what works as of end of 2018 under the assumption that

<ol>
<li>You want to install the GPL version of OpenJDK.[0]</li>
<li>You do not want to install Homebrew</li>
</ol>

In that case, grab the desired version from one the many available, freely usable OpenJDK editions, e.g.:

<ul>
<li><a href="https://adoptopenjdk.net/" rel="nofollow noreferrer">AdoptOpenJDK</a></li>
<li><a href="https://aws.amazon.com/corretto/" rel="nofollow noreferrer">Amazon Corretto</a> (Great for production, includes <a href="https://docs.aws.amazon.com/corretto/latest/corretto-11-ug/patches.html" rel="nofollow noreferrer">backports</a>)</li>
<li><a href="https://jdk.java.net/" rel="nofollow noreferrer">Oracle GPLv2 OpenJDK</a></li>
</ul>

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:

<pre><code>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
</code></pre>

[0] Note that the Oracle branded JDK has <a href="https://www.oracle.com/technetwork/java/javase/terms/license/javase-license.html" rel="nofollow noreferrer">significant licensing restrictions</a> 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 <a href="https://stackoverflow.com/a/38685948">differences to OpenJDK are minimal</a>.

Edit: added more choices

I think this other Stack Overflow question could help:

<a href="https://stackoverflow.com/questions/2846573/how-to-get-jdk-1-5-on-mac-osx">How to get JDK 1.5 on Mac OS X</a>

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 <code>-source 1.5</code> and/or <code>-target 1.5</code> in the javac options or in your IDE.

JDK is the Java Development Kit (used to develop Java software).

<a href="https://en.wikipedia.org/wiki/Java_virtual_machine" rel="nofollow">JRE</a> 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.

blocks|key|1067471|text|一般来说，除了Apple通过Software提供的版本之外，您不能在Mac上安装其他版本的Java。如果你需要Java+6，你必须有一台64位英特尔电脑.如果您至少安装了OSX10.4，那么您应该始终安装Java+5和1.4，也许还应该安装1.3。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1067472|如果你有太多的麻烦，并且愿意使用测试版软件，你可以在OS下安装OpenJDK，但我认为你不想去那里。|1067473|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

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.

I want to install a specific JDK (the latest for example). For this, I went to the JDK download homepage: <a href="http://java.sun.com/javase/downloads/index.jsp" rel="noreferrer">http://java.sun.com/javase/downloads/index.jsp</a>.
I looked for a Mac version, but I'm a bit surprised to only see downloadable versions for Linux, Windows and <a href="http://en.wikipedia.org/wiki/Solaris_%28operating_system%29" rel="noreferrer">Solaris</a>...

Here's the message for Mac:

<blockquote>
 "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."
</blockquote>

OK BUT... when I update Java with Mac I have a <a href="https://en.wikipedia.org/wiki/Java_virtual_machine" rel="noreferrer">JRE</a> 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...

How to install a specific JDK on Mac OS X?

我想安装一个特定的JDK (例如最新的)。为此，我访问了JDK下载主页：。我寻找一个Mac版本，但我有点惊讶，只看到可下载版本的Linux，视窗和.下面是给Mac的信息：“苹果电脑提供他们自己的Java版本。使用软件更新功能(可在苹果菜单上找到)来检查您的Mac中是否有最新版本的Java。”好吧但是..。当我用Mac更新Java时，我有一个，而不是JDK.我不明白为什么JDK版本不存在可以轻松下载
