Error Class names are only accepted if annotation processing is explicitly requested

Do you get the following error?

Class names, 'Hello', are only accepted if annotation processing is explicitly requested

1 error

In case you got this error, then you forget to add .java to the file name when you compile it

So when you want to compile a file using cmd console window write the filename.java extension

Example:

Javac Hello.java

If you write it in this way the error will go away. So don’t forget to include suffix with your file name during compilation.
