Downgrade to Java 8 from Java 10 on Mac so that Netbeans can work
I have java version 8, but when I type java -version in terminal I am getting java 10 version. I want my java version 8 back.
In System Preferences, it is Showing Java 8 but when I see in terminal it is showing that I am using Java 10.0.2 version.
Netbeans is not working, i.e On clicking New Project no operation is performed.

I assume that you are using NetBeans 8.2, since that release will not work with any version of Java > 8.
If so, then you need to tell NetBeans to use Java 8 (and not Java 10) on startup. To do that:
- Close NetBeans 8.2 if it is running.
- Within your NetBeans 8.2 installation directory locate a directory named etc.
- Within that directory locate a configuration file named netbeans.conf.
- Open that file in any text editor. It is a simple text file containing property-value pairs.
- Locate the line containing the property
netbeans_jdkhome. If that line is prefixed with a#symbol (to denote a comment) then remove that#. - Replace whatever the value is for that property with the path to your JDK 8 installation. For example, on my Windows 10 machine that line looks like this for my NetBeans 8.2 installation:
netbeans_jdkhome="C:Javajdk1.8.0_181"
- Save your changes to
netbeans.confand start NetBeans. You should now be able to create a project in NetBeans 8.2 using JDK 8.
One final point: it doesn't matter what value is returned for java -version in a Terminal window. All that matters for NetBeans 8.2 to work is that it is configured to use Java 8.
