You can even install it by downloading it with your web browser and installing it from your desktop, but in my opinion, Homebrew is the easiest way to install it and ensure you get the latest version. Yes, there are other ways to install Java without Homebrew. FAQsīelow are a few questions I often see when talking about Java installations. It contains the javac compiler, libraries, and other components you need to create a java application that will run on JRE. This is a set of tools that you need to develop applications in Java. It is used to run any java apps you write and java applications you might download.
This is the part of Java that actually runs Java applications and applets. You may understand that they are part of Java but may also wonder what the difference is between them. When working with and installing Java, you may see references to JRE and JDK and wonder what these are. In the example above, it would be 18.0.1.1. You should get a response showing the same version as the java version you just installed. You will see a command not found message or something similar if it is not installed. If you already have it installed, it will come back with the current version on your machine.
You can check if you currently have Java installed with the following command. You could proceed with the new install if there is a more recent version and you wish to upgrade. If there is another version, you may want to take note of the version. There’s a chance it could have already been installed by another application. Before starting the installation, I first recommend checking to see if you already have a version of Java on your Mac. Once you install Homebrew, you are now ready to install Java.

RUNTIME JAVA FOR MAC UPDATE
MacOS Software Update itself works and shows that my Mac is up to date.It will give you a response showing the version if you already have it installed. I tried to use the router at home (FritzBox), and I also used tethering via my iPhone as a personal hotspot (and this in turn using mobile data via its SimCard) - just to rule out the possibility that my FritzBox is blocking some ports which are needed for the update. Internet connection itself (wireless) works fine. It seems that the Java Control Panel can not access the information from the internet. This stays like this for arbitrary time (at least for 15 minutes - after this, I lost the patience). However, on top of the panel is only shown something like a rotating circle, most likely indicating that information is being fetched from the internet. I would now expect to be shown a new Java version, if one is available. I went to SystemPreferences/Java and the Java Control Panel opens. Since I'm running applications which require a higher Java version ( jEdit for instance), I want to update Java.
