What is sealed class?

Answer:

Sealed classes are those classes which can not be inherited and thus any sealed class member can not be derived in any other class. A sealed class cannot also be an abstract class.

class ClassSeal 



{ 



    static void Main(string[] args) 

    { 

       SealedClass sealedCls = new SealedClass(); //Sealed class declaration

        int total = sealedCls.Multiple(14, 53); 

        Console.WriteLine("Total = " + total.ToString()); 

    } 



} 



// Sealed class Definition

    public int Multiple(int x, int y) 

    { 

        return x * y; 

    }
