Using the Command-line to find Java Versions - Mac
The Java Runtime (JRE) that you download from java.com or oracle.com contains a plugin to run Java content from your browser. In order to use the command line tools, you will need to download the Java Development Kit (JDK). The JRE and JDK are separate and can coexist on your system. Only one JRE can be installed on Mac. There can be multiple JDKs installed on a system, as many as you wish.
JRE Version Command Line on Mac
Type the following in a Terminal window: /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version
Determining the Default Version of the JDK on Mac
When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.
You can determine which version of the JDK is the default by typing java -version
in a Terminal window. If the installed version is 7u55, you will see a string that includes the text 1.7.0_55
. For example:
java -version
java version '1.7.0_55'
Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)
Changes introduced with macOS 10.15 (Catalina) cause certain Java applications to behave incorrectly. Therefore, we cannot certify any JDK version on macOS 10.15 yet.

When you install or run software for the first time, Gatekeeper verifies that the software has been notarized. See Notarizing Your App Before Distribution.
However, as of now, you can install and run non-notarized software on macOS 10.15 systems by modifying your security preferences. The following steps show you how to install a non-notarized JDK or JRE.
