What is the correct declaration for an abstract method 'add' in a class that is accessible to any class, takes no arguments and returns nothing?

beter say in an abstract class and not just class

I think the clarification is important—I would declare it in an abstract class as public abstract void add(); so it’s accessible everywhere, takes no arguments, and returns nothing. I like how precise wording matters here, because a small detail can change the whole meaning. Veck IO
