What does public static void main() throws IOException mean?
That makes sense. Is the "public" keyword necessary in this context?
It depends on how you want to use the main method. If you want the method to be accessible by any other class, then you must use the "public" keyword. If you want to restrict access to the main method only within the same package, then you can use the "protected" or "default" keywords instead.
