You can click on Search present on taskbar or press Ctrl + Q.
Search "Configure Java" and click on it.
That should open the Java Control Panel.

The only solution that I have come up with in a similar situation: to uninstall & re-install Java.

It's possible that this issue has something to do with what happens when Java update loads a new version to your system. I am saying this because Java by default tends to install itself into directories where the directory name has the version number. So a change in version number => changes the installation directory => may have an effect on some paths were system expects to find Java.

I am not sure if this is the cause however but so as to remove that possibility, when I re-installed Java I created a custom directory C:\Program Files\Java\JDK (this was the 64-bit version; a 32-bit version should have been placed in C:\Program Files (x86)) and directed the installer to put everything in that directory (instead of its default which would have been something like: C:\Program Files\Java\jdk_1.8.0.66).

If you are installing just the JRE then the custom path could be something like C:\Program Files\Java\JRE (instead of the default C:\Program Files\Java\jre8).

When you uninstall Java, make sure that:

• The Java directories (in either C:\Program Files (x86)\Java or C:\Program Files\Java) are actually deleted by the uninstaller. If not, it's better to delete them manually (since you will be re-installing them anyway, this should be fine).
• Any environment variables (e.g. JAVA_HOME, PATH, etc) that refer to the old location actually point to the new location

Is there a program ANY WHERE that will replace Java?  I have nothing but problems with it ... I thot it was an Oracle problem but did Microsoft purchase it.  My problem is that I'm OLD and cannot concentrate on a billion instructions, especially not as confusing as the instructions for Java AND it would help if the java updates would work ... everything on my computer works flawlessly, except Java.  I'll pay someone to get it out of my computer and install a program that WORKS ... plus Java is full of bugs ... and the updates don;t work so it is destroying my security.  Help Mr. Wizard please make EVIL MICROSOFT go away and bring NICE Microsoft, back when it worked ...

Here's a solution that worked for me:

1. Open a new finder window and navigate to /Library/Internet Plug-Ins/. There you will find a file named JavaAppletPlugin.plugin.
2. Control + Click this file and choose Show Package Contents from the contextual menu.
3. Inside the package, navigate to /Contents/Home/bin/.
4. Double click the ControlPanel file to display the Java Control Panel. Change any settings as you wish and then save it.
5. From now on, the panel will be available as always from “Apple” menu > System Preferences...

Note: if you don't find the JavaAppletPlugin.plugin file inside the /Library/Internet Plug-Ins/ folder, open the Terminal.app and create a symlink from the original:

sudo ln -s /System/Library/Java/Support/CoreDeploy.bundle/Contents/JavaAppletPlugin.plugin /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

Reference

According to the Oracle Java 16 documentation, the Control Panel was removed in Java 11.

It may or may not be present in other Java distros. If it is still present, you should be able to find it as ControlPanel or jcontrol in the Java installation's bin or jre/bin directory. (Or javacpl.exe + javacpl.cpl on Windows.)

However as @Holger notes, it is doubtful that you would be able to use the Control Panel to update Java (for Java 11 and later) anyway. The standard Control Panel relies on Oracle-managed update servers, and it is unlikely that those servers would (or could) serve upgrades for a 3rd-party Java distro.

You are better off updating Java some other way; i.e. by downloading and running the Windows installer.

(Note that Oracle want vendors of Java-based applications to take responsibility for distributing their Java platform to end users; e.g. by shipping custom JREs generated using jlink. If you are still advising your users / customers to upgrade Java via the Control Panel, you are "doing it wrong" ... since Java 9.)

It may be a simple case that it isn’t installed.
