Please copy the full text of the error message and paste it here. It has important info about the error.
I don't know what "editor does not contain a main type" means.
Can you explain how you are trying to execute the program. Are you using an IDE?
If you don't understand my answer, don't ignore it, ask a question.
It means there is no main class to run the program, you need to set a main class before running it.
