How to install Java 8 on Mac

Editors note: This question was asked in 2014, and the answers may be outdated.
I want to do some programming with the latest JavaFX, which requires Java 8. I'm using IntelliJ 13 CE and Mac OS X 9 Mavericks. I ran Oracle's Java 8 installer, and the files look like they ended up at
/Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk
but previous versions are at
/System/Library/Java/JavaFrameworks/jdk1.6....
Not sure why the latest installer puts this in /Library
instead of /System/Library
(nor what the difference is). But /usr/libexec/java_home
doesn't find 1.8, so all the posts I've found on how to set your current java version don't work. I've tried adding a symbolic link to make it look like 1.8 is in the /System/Library...
path, but it doesn't help. /usr/libexec/java_home -V
still only lists the old Java 1.6.
Ironically, the "Java" control panel under System Preferences shows only Java 1.8!
Why doesn't Oracle's installer put it where it really goes? And how can I work around this problem?
Oracle has a poor record for making it easy to install and configure Java, but using Homebrew, the latest OpenJDK (Java 14) can be installed with:
brew install --cask adoptopenjdk8
For the many use cases depending on an older version (commonly Java 8), the AdoptOpenJDK project makes it possible with an extra step.
brew tap adoptopenjdk/openjdk
brew install --cask adoptopenjdk8
Existing users of Homebrew may encounter Error: Cask adoptopenjdk8 exists in multiple taps
due to prior workarounds with different instructions. This can be solved by fully specifying the location with brew install --cask adoptopenjdk/openjdk/adoptopenjdk8
.
Note: Oracle Java 8/9/10 is no longer available for public download (license change).
First install and update brew from Terminal:
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew tap homebrew/cask-versions
brew update
NEW as of June 2019
To install the JDKs from AdoptOpenJDK:
brew tap adoptopenjdk/openjdk
brew install --cask adoptopenjdk8
brew install --cask adoptopenjdk9
brew install --cask adoptopenjdk10
brew install --cask adoptopenjdk11
OLD
Java 8:
brew install --cask java8
Java Latest:
brew install --cask java
