When is sealed better to use than protected?

Question

When and where is a sealed class good to use. What's a good application of sealed classes?

Answer 1

when you don't want a class be inheritable you use sealed modifier, for example when you don't want other programmers inherit from your class or when you have static members in class.
when you use protected modifier, only derived classes can call the class members, no any other classes.
