Run .java file directly using cmd on Mac Terminal

Question

I have a folder consisting some .java files. Instead of building a new java project, I run one of the .java files hellowworld.java using terminal:

java hellowworld

But it gives me could not find or load main class helloworld. What should I do?

Yes, it says: Class names, 'hellowworld', are only accepted if annotation processing is explicitly requested — Meteorite

According to this docs.oracle.com/javase/tutorial/getStarted/problems that means you forgot to put '.java' in the command.
