How To Check If I Have Java Installed On Mac

Question

I take gone into Terminal and typed

                java -v

for which it responds with

                No Java runtime present, requesting install.

But I am not sure if that is confirming if Java is not installed or whether the Java SDK is not installed.

Are you trying to bank check if the JDK or JRE is installed? — Sep 15, 2022 at 15:56

If it'south responding with No Java runtime present, requesting install.... well, it's not installed. I believe that Apple's default installer still installs Java vi; I'd recommend getting the latest version (right now Java 8u144) from here.

With Java eight, java -5 fails with Unrecognized option: -v. Use java -version instead.

@Mark Don't call up then, should be the JRE. Not 100% tho.

Many versions of Java for macOS install an entry into the Arrangement Preferences. If y'all accept a Java icon in System Preferences, information technology's highly likely that Java is installed on the Mac:

That is only for the JRE used in a browser

@Mark, I have the total Coffee 8 JRE installed on my Mac (not simply browser support). The Java system preference pane shows upward as office of the install. So, the system preference pane is included with Coffee installations that cover more than than just the browser.

I think that panel only covers the browser install - look at the settings in information technology. Besides the Coffee JRE for OSX does non support the command line. I retrieve y'all take to install the full JDK (although there might be a version in between)
