The version 8 release from Oracle (1.8.0_40-b25) can be found at:

/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home/bin/java

FYI: Oracle is not following the practice of making /Library/Java/Current (etc) a link to the latest installed java.

Below is my method of keeping up with versions over time: from my .zshrc file:

108 JAVA_6_HOME=/System/Library/Frameworks/JavaVM.framework/Home
109 JAVA_7_HOME=/Library/Java/Current
110 JAVA_8_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home
111 
112 export JAVA_6_HOME
113 export JAVA_7_HOME
114 export JAVA_8_HOME
115 
116 export JAVA_HOME=$JAVA_8_HOME
117 
118 PATH=$PATH:$JAVA_HOME/bin

Enough answers here, but I'm JUST adding a way to find it by yourself

$ sudo find / -name Java
/Library/Application Support/Oracle/Java
/Library/Java
/private/var/root/Library/Application Support/Oracle/Java
/System/Library/Java
/Users/prayagupd/Library/Application Support/Oracle/Java

To be more specific, 

$ sudo find / -name jdk*
/Applications/Android Studio.app/Contents/jre/jdk
/Applications/Android Studio.app/Contents/lib/jdkAnnotations.jar
/Applications/IntelliJ IDEA.app/Contents/jre/jdk
/Applications/IntelliJ IDEA.app/Contents/lib/jdkAnnotations.jar
/Library/Java/JavaVirtualMachines/jdk1.7.0_76.jdk

You see /Library/Java/JavaVirtualMachines/ is the place you need to look inside.

And /Library/Java/JavaVirtualMachines/jdk<version>.jdk/Contents/Home/ is your JAVA_HOME

$ ls -ls /Library/Java/JavaVirtualMachines/jdk1.7.0_76.jdk/Contents/Home/
total 39776

The JDK/JRE as mentioned in previous answers is located in /Library/Java/JavaVirtualMachines/<version>/Contents/Home/. The JRE is dir under this Home. Interestingly browsers doesn't use files from this location for java applet plugin. The location used by browsers is /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/. In fact if you run JRE installer, it updates the files in this location rather than JDK/JRE location.

Some of the other answers might be correct but this is what worked for me (which is different and up to date as of January 2016) when installing it on a new computer at the office.

The path as mentioned in another answer is 

/Library/Java/JavaVirtualMachines/<Replace with version>/Contents/Home

Here however is a visual guide to getting there, because you can find many directories named "Library". Make sure you are here

enter image description here


then click into JavaVirtualMachines

enter image description here


If you are doing a new setup and just downloaded Android studio, they might have sent you to "Download Java for OS X 2015-001" at https://support.apple.com/kb/dl1572?locale=en_US
That gives you version 1.6.0

enter image description here

That won't work!!!!

I got the error that I needed JDK 7.0 or newer.

I looked for a newer version and found this link from Oracle http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html

enter image description here


I installed it, then selected that one. And it worked

If you setting the JRE path in something like Eclipse you'll need to point to the /home directory i.e

/Library/Java/JavaVirtualMachines/<Replace with version>/Contents/Home

The Oracle Java SE downloads at: http://www.oracle.com/technetwork/java/javase/overview/index.html

install here on Maverick at least:

/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/

this JRE is entirely separate from the ones that Apple has installed, which are under /System/Library/Frameworks/JavaVM.framework/Versions/ as another answer mentioned.

On my system, evaluating which java leads me to /usr/bin/java. This in turn is a symlink to:

/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

In case it's relevant, java -version tells me I have 1.6.0_37 installed.
