Java package structure of Mac OS is a bit different from Windows. Don't be upset for this as a developer just needs to set PATH and JAVAHOME. So in.bashprofile set JAVAHOME and PATH as below. This example is for Java 6. Java runtime mac free download - Java Runtime Environment (JRE), Java Runtime Environment (JRE) (64-Bit), Java Runtime Environment (JRE) for Fedora (32-bit ), and many more programs. It was originally developed by Sun Microsystems. Unlike Windows, Mac OS, Unix, or Unix-like systems which are primarily written in the C programming language, JavaOS is primarily written in Java. It is now considered a legacy system. As for the Java Update for Mac OS X 10.4, Release 8, Apple says the new software ”delivers improvements to the security and compatibility of Java on Mac OS X 10.4.11 and later.”.
The following are the system requirements for installing the JDK and the JRE on macOS:
Any Intel-based computer running macOS.
Administrator privileges.
You cannot install Java for a single user. Installing the JDK and JRE on macOS is performed on a systemwide basis for all users. Administrator privileges are required to install the JDK and JRE on macOS.
When you install the JDK, it also installs the JRE. However, the system will not replace the current JRE with a lower version.
To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.
When you install the JRE, you can install only one JRE on your system at a time. The system will not install a JRE that has an earlier version than the current version.
To determine the current JRE version installed on your system, see Determining the JRE Version Installed on macOS. To install an earlier version of the JRE, you must first uninstall the current version. See Uninstalling the JRE on macOS.
Note:
Installing a JRE from Oracle will not update
java -versionsymlinks or addjavato your path. To do this, you must install the JDK.

- Watch the companion video: How to use Java in the new Microsoft Edge
Some users may need internet artifacts like the Java browser plugin to run legacy apps that require it. The options to run Java apps are few and far between these days. Yet it is possible to use Microsoft’s new Edge web browser — the Chromium-based version of Edge — to run Java apps. Assuming you have Java installed on your computer, the only requirement is an intermediary in the form of an extension.
What makes Java support possible in the new Chromium-based Microsoft Edge is Edge’s support of Chrome extensions. If you are still running the old version of Edge, it handles the need for running Java apps in a completely different way. Although Microsoft has its own extensions library, you won’t find what you are looking for there. Edge users with Java needs must visit the Chrome Web Store instead to install the one discussed here.

Java in the new Microsoft Edge using IE Tab
One method to use Java in the new Microsoft Edge is to install the IE Tab extension. The “IE” in IE Tab is an abbreviation for Internet Explorer. Available for Edge from the Chrome Web Store, IE Tab emulates Internet Explorer within an Edge browser window. The extension uses the Internet Explorer rendering engine to display Java content (as well as ActiveX and Silverlight content). It is easy to install, and even easier to use. It is important to note that IE Tab works on Windows machines only.
Visit the IE Tab page in the Chrome Web Store. Click the blue Add To Chrome button. A dialog will display asking you if you want to Add IE Tab, accompanied by a list of functions it can perform. Click the Add extension button.
Once installed, the IE Tab icon in Microsoft Edge displays next to Edge’s address bar. Click the icon to open an IE Tab. In the IE Tab, input the web address of a page that contains Java content. In the example below, our Java version verification was successful. The page uses a Java detection applet, with the latest version of Microsoft Edge using an IE Tab.
Try that same verification process in a regular Edge tab, and a notification that, “We are unable to verify if Java is currently installed and enabled in your browser,” displays instead.
Java Web Start, No Browser Required
If you have the Java plugin on your Windows machine, then you have Java Web Start (JWS). The question is does the Java application you want to run use JWS technology? JWS launches automatically if you download a Java app that uses it (usually in the form of a .jnlp file). Check the Java app developer’s website to see if they have a JWS download link for their app. If they do, download it and save a shortcut on your desktop when prompted by JWS. Double-click the shortcut to run the app.
Also included with JWS is a Java Cache Viewer. Use Cache Viewer to launch applications you have already downloaded. Here’s how:
1. Launch the Java Control Panel (Control Panel > Programs > Java icon). Double-click the Java icon.
2. Under the General tab, click the View button in the Temporary Internet Files section to launch the Java Cache Viewer in a separate window.
3. Double-click an application listed in the Java Cache Viewer to launch it without needing a web browser.
If the Java app you want to use is not listed or does not launch when double-clicked, contact the app’s developer.
