Since OS X 10.7 Java is not (pre-)installed anymore, let's fix that. As I'm writing this, Java 11.0.4 is the latest version and AdoptOpenJDK is one of the best places to find Prebuilt OpenJDK Binaries. Easy to follow details about how to install OpenJDK are available here.
However, the easiest way is to select OpenJDK 11 (LTS), the HotSpot JVM, and macOS x64, which will expose two option like these:
Clicking on 'Install JDK installer', will download the OpenJDK installer package, e.g. OpenJDK11U-jdk_x64_mac_hotspot_11.0.4_11.pkg, which when executed, will install into this location: /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk
Update for Java Runtime Environment for Mac (1.8.191) Bulletin Id: MAC-033: Bulletin Title: Java Runtime Environment 8 Updates For Mac: Severity: Critical: Location Path: jre-8u191-macosx-x64.dmg: Bulletin Summary: Java Runtime Environment 8 Updates For Mac: Superceding Bulletin Id: MAC-033: Patch Release Date: Oct 17, 2018: Affected Product. Oracle Java for Mac or Java 7 JRE/Java SE Runtime Environment 7 is the official version of Java for Mac by Oracle that allows you to run Java applications and games, both in your web browser and within the OS X Desktop. Because of security concerns, its only recommended that you install Java for Mac if you really need it. Up until now, Apple has its own version of Java, which is out of step.
Almost done. After opening a terminal, the successful installation of the JDK can be confirmed like so:
… hopefully showing something like this:
JAVA_HOME is an important environment variable and it's important to get it right. Here is a trick that allows me to keep the environment variable current, even after a Java Update was installed. In ~/.zshrc, I set the variable like so:
In previous macOS versions, this was done in ~/.bash_profile. Now it's done.

Mac OS Runtime for Java (MRJ, originally Macintosh Runtime for Java) was Apple's proprietary virtual machine for Java-based applications in the classic Mac OS (i.e. versions prior to Mac OS X). Both a runtime environment and a software development kit (SDK) are available.
Java Runtime Environment Mac Os Sierra
The runtime environment includes a JIT compiler developed by Symantec, the standard Java class library from Sun, additional classes providing Macintosh-specific functionality, and the Apple Applet Runner (a lightweight application for running Java applets without the overhead of a web browser). A number of web browsers could use MRJ to run Java applets in web pages, including MicrosoftInternet Explorer, iCab and HotJava. Picture viewers for mac.
The SDK includes ports of most of the tools from Sun's Java Development Kit (in the form of MPW tools and Macintosh applications), additional tools for packaging Java applications as double-clickable Macintosh applications, libraries for Macintosh-specific functionality, and documentation for the MRJ-specific classes and tools.
MRJ v2.2.5 was compatible with Sun's Java Development Kit version 1.1.8.[1]
Oracle Java Archive. Besides setting -source and -target, you need to grab the core library jar files (e.g., rt.jar, jce.jar, jsse.jar) of earlier jdk versions, and then set -bootclasspath to those files when using javac. Jar files from operating systems other than Mac usually also work. – dacongy Apr 29 '12 at 5:08.
Since the transition to Mac OS X, Apple has discontinued MRJ and instead maintains and distributes a port of Oracle'sHotSpot Java virtual machine.[citation needed]
