@timmy4all : For all submissions in JAVA on CodeChef , you should name your class “Main” and nothing else if your class is “public” . If you don’t declare the class “public” then you can name your class anything you want . Because whether you upload a file or paste code while submitting to the “online judge” copies its contents to Main.java .
