You can determine which version of the JDK is the default by entering java -version in a Terminal window. If the installed version is 15 Interim 0, Update 0, and Patch 0, then you see a string that includes the text 15. For example:
Some applications use /usr/bin/java to call Java. After installing Java for macOS 2012-006, /usr/bin/java will find the newest JDK installed, and will use that for all of the Java-related command-line tools in /usr/bin. You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application.
You can determine which version of the JDK is the default by entering java -version in a Terminal window. If the installed version is 9 Minor 1, Security 1, Patch 1, then you see a string that includes the text 220.127.116.11. For example:

Not sure why the latest installer puts this in /Library instead of /System/Library (nor what the difference is). But /usr/libexec/java_home doesn't find 1.8, so all the posts I've found on how to set your current java version don't work. I've tried adding a symbolic link to make it look like 1.8 is in the /System/Library... path, but it doesn't help. /usr/libexec/java_home -V still only lists the old Java 1.6.
When I visited \"More Info,\" it allowed me to download the latest java package, but it didn't work and I continued to receive the message. I went to Apple's website to resolve the issue (below) and downloaded the legacy package.
In this step, we will test whether Java is already installed or not. To do so, open the terminal and type java -version as shown in Fig 1. If Java is already installed on the system, it will show the active version details as shown in Fig 1.
Prerequisite, Java must be available:Java is open source and can be downloaded from SQuirreL will always run with the current LTS (Long Term Support) release of Java.The minimum Java version required usually is the previous LTS release.Installation of the SQuirreL SQL Client on Windows and Linux/Unix:The SQuirreL SQL Client can be installed by the IzPack installer. Download the file squirrel-sql--standard.jarand execute it using the following command:java -jar squirrel-sql--standard.jar when you properly installed Java.or\\bin\\java -jar squirrel-sql--standard.jar when you just unpacked the zip or tar.gz version of Java.Note: On Linux/Unix replace backslashes (\\) by slashes (/).Make sure that you have write privileges to the directorythat you want to install into.Note that some browsers may attempt to open thisfile rather than download it. In this case, right-click onthe download link and click your browser's equivalent of the\"Save as...\" menu item.Installation of the SQuirreL SQL Client on MacOS:On MacOS the preferable way to install the SQuirrel SQL Client is the MacOS X installer squirrel-sql--MACOSX-install.jar.Starting the SQuirreL SQL Client:On Windows, execute the file squirrel-sql.bat to run theapplication. On Linux/Unix and MacOS, the file is squirrel-sql.sh.Trouble shooting:When SQuirreL SQL doesn't start:On Windows try to add the line  set JAVA_HOME=to the top of squirrel-sql.batOn Linux/Unix or MacOS try to add the line  export JAVA_HOME=after the line  #! /bin/shof squirrel-sql.shScaling problems on high resolution screens:Set the JVM (Java Virtual Machine) parameter-Dsun.java2d.uiScale=Example: -Dsun.java2d.uiScale=2.5This can be done by editing squirrel-sql.bat on Windows and squirrel-sql.sh on Linux/Unix or MacOSor by setting the SQUIRREL_SQL_OPTS variable before executing the start script.
The OpenJDK project itself is managed on openjdk.java.net where you can find specifications, source code, and mailing lists, but there are no builds that you can download.You need to choose a distribution.
Now the only two things that you will need are: the opencv-3xx.jar file located at \\opencv\\build\\java and the opencv_java3xx.dll library located at \\opencv\\build\\java\\x64 (for 64-bit systems) or \\opencv\\build\\java\\x86 (for 32-bit systems). The 3xx suffix of each file is a shortcut for the current OpenCV version, e.g., it will be 300 for OpenCV 3.0 and 330 for OpenCV 3.3.
To install OpenCV (with Java support) through Homebrew, you need to edit the opencv formula in Homebrew, to add support for Java:brew edit opencvIn the text editor that will open, change the line:-DBUILD_opencv_java=OFFin-DBUILD_opencv_java=ONthen, after saving the file, you can effectively install OpenCV:brew install --build-from-source opencv
After the installation of OpenCV, the needed jar file and the dylib library will be located at /usr/local/Cellar/opencv/3.x.x/share/OpenCV/java/, e.g., /usr/local/Cellar/opencv/3.3.1/share/OpenCV/java/.
Now open the terminal, go to the build folder of OpenCV and compile everything with the command: make -j. Notice that the -j flag tells make to run in parallel with the maximum number of allowed job threads, which makes the build theoretically faster.Wait for the process to be completed...If everything went well you should have opencv-3xx.jar in the /opencv/build/bin directory and libopencv_java3xx.so in the /opencv/build/lib directory. The 3xx suffix of each file is a shortcut for the current OpenCV version, e.g., it will be 300 for OpenCV 3.0 and 330 for OpenCV 3.3. This is everything you need.
In case of MacOS, if you installed OpenCV without Homebrew, you need to create a soft link with .dylib extension for the .so file. E.g., from the terminal, type:ln -s libopencv_java300.so libopencv_java300.dylib
In this case, /Applications/sqlcl/bin/sql is the full path, hr is the username, and oracle is the password. Those credentials were created when I installed Oracle on my Mac using the Oracle DB Developer VM.
First, open Google and type the java plugin mac download in the search button. Then select the Java Plug-in Mac Download Page - Oracle. 076b4e4f54
