The reason for this error could be that you don’t have Java at all in your PC or JAVA_HOME and PATH variables are not set up properly.

In my case, my PC was not having Java installed. So I went with OpenJDK from Eclipse foundation. So by performing the following steps, it solved the problem.

• Download AdoptOpenJDK, I selected .msi version for my x64 PC.
• On the Custom Setup screen, select “Set JAVA_Home variable” and “JavaSoft (Oracle) registery keys”
  

• Let the installer setup JAVA_HOME and PATH system variables

• Give a restart to your PC (better do it with Windows :p)
• Verify in command prompt to see if this JDK version is reflecting

• Run your application.
