    Sealed Class 

    Sealed class is used to define the inheritance level of a class. 

    The sealed modifier is used to prevent derivation from a class. An error occurs if a sealed class is specified as the base class of another class.


    Some points to remember:  
    1.  A class, which restricts inheritance for security reason is declared, sealed class.
    2.  Sealed class is the last class in the hierarchy.
    3.  Sealed class can be a derived class but can't be a base class.
    4.  A sealed class cannot also be an abstract class. Because abstract class has to provide functionality and here we are restricting it to inherit.
