I am using a 32 bit windows 7 OS and I have installed JDK 8 as it was the only available JDK version for a 32 bit system. I have also given the path in the environment variables. But, when I am trying to check the java version in the command prompt typing java --version, I am getting a fatal error.
You should double check if your path variable is set correctly. It should point to the ...\bin\ directory where the 'java.exe' is located. Because thats whats called with 'java --version'.

When I run on console javac -version, I get the version number as 11.0.2, but when I run java -version I get the following error:
Error: opening registry key 'Software\JavaSoft\Java Runtime Environment'
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.
What should I do about this?
Which version of JRE do I need to install for JDK 11.0.2,so that I won't get any compatibility issues which executing java code?
Check path.
To make sure that Windows can find the Java compiler and interpreter:
Select Start -> Computer -> System Properties -> Advanced system
settings -> Environment Variables -> System variables -> PATH.
Prepend C:\Program Files\Java\jdk1.x.x\bin to the beginning of the PATH variable.

I have developed a JAVA application for signature verification and I want to develop an Apache Nifi Processor for this JAVA application.
When I want to run .bat file in cmd i.e. run-nifi.bat I get this error :
"The JAVA_HOME environment variable is not defined correctly. Instead
the PATH will be used to find the java executable."
Also I can not find my processor at http://localhost:8080/nifi
Just define JAVA_HOME system environment variable and point it to your JDK dir. More detailed answer: How to set java_home on Windows 7?
