The java-1.8.0-openjdk package contains just the Java Runtime Environment. If you want to develop Java programs then install the java-1.8.0-openjdk-devel package. JDK 7 Debian, Ubuntu, etc. On the command line, type: $ sudo apt-get install openjdk-7-jre. The openjdk-7-jre package contains just the Java Runtime Environment. How to install Java JDK Java Development Kit on mac. In Mac OSX 10.5 or later, Apple recommends to set the $JAVAHOME variable to /usr/libexec/javahome, jus.
Java Runtime Environment 1.6.0 64 Bit
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
Download Jdk For Mac
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.

While no one is going to put Java Runtime Environment at the top of their best software list, it is essential if you want to run any Java-based applications or web applets. It’s probably easiest to conceptualize if you think of it as a virtual environment rather than a tech tool, and there’s a good chance it’s already installed on your computers. If it’s not, get downloading, because most of the internet won’t work without it.
A basic necessity for most computers
The essential download for Java applications
Java Runtime Environment or JRE is Java’s programming language. It’s really a type of virtual environment in which this programming language can run and it’s a required component whenever you do run a Java application. In fact, there’s a chance it’s already installed on your machine, although you will probably need to download it separately under certain circumstances.
It would be wise to point out that most users will never need to actually use this tool it just needs to be present on their computers. That’s just as well, as the actual interface is... well, quite plain is probably the nicest thing we can say. It’s a classic Windows interface and you access the different parts of it via tabs along the top of the window. Even though it’s very unappealing, it’s not at all difficult to get around.
Installing it couldn’t be easier. You download the file, follow the installer instructions, and you’ll have Java on your computer and ready to go. The default settings will be more than enough for most users, but in the event you need more control over how Java acts or integrates, you can use the options you’ll access via the control panel.
Although Java seems very dull to the inexpert eye, if you’re a programmer, you can actually use it to develop some pretty cool things. Java can be used to make application servers, unit tests, mobile apps, and desktop, web and enterprise apps. To actually create any of these things, you’ll need to learn about Java programming first (the JRE by itself can’t actually create anything), but it could be an interesting project to carry out in your spare time.
Sure, when you have a look around the JRE, you’re unlikely to be too impressed, but just remember that this underwhelming little gray box powers more than 15 billion devices all around the world, making it the most popular programming language on the planet.
If you’re unsure if you have Java already on your computer, or you want to check that you have the most recent version, you can head over to the Java website and perform the Verify Java Version test. If you’re good to go, you can rest easy, and if you see you’re missing something, you’ve got everything you need to download here.
Where can you run this program?
Java for desktop runs on Windows, Mac, Linux, and Solaris. This version is for Windows.
Is there a better alternative?
Jre For Mac
Unfortunately not! If you want to run Java applications on your computer (and whether you’re aware of it or not, a great number of things you do online are powered by Java), you’ll need the Java Runtime Environment there is no alternative.
Our take
Java Runtime Environment is a mysterious and seemingly underwhelming tool for most users. If you fall into this group, just accept that you need it on your computer and move on. If you’re excited about the possibilities of Java, however, you’ll very much enjoy knowing that it’s up-to-date and ready to go on your machine.
Should you download it?
In the unlikely event you don’t have Java on your computer, you definitely need to download it to allow your computer to work as desired.
