Answer / vishal
Sealed Class:
When applied to a class, the sealed modifier prevents other
classes from inheriting from it. In the following example,
class B inherits from class A, but no class can inherit
from class B.
class A {}
sealed class B : A {}
You can also use the sealed modifier on a method or
property that overrides a virtual method or property in a
base class. This enables you to allow classes to derive
from your class and prevent them from overriding specific
virtual methods or properties.
Private Class :
Classes and structs that are not nested within other
classes or structs can be either public or internal. A type
declared as public is accessible by any other type. A type
declared as internal is only accessible by types within the
same assembly. Classes and structs are declared as internal
by default unless the keyword public is added to the class
definition. And yes, a class cannot be private unless of
course if it a nested class.

continuation from the prev.post...
We can put the "private" keyword, if and if only the class
is in public class.. It is rarely used..
public class a
{
...
private class b
{
..
}
}
otherwise, we can not put private keyword over the classes
directly..

Answer / robert j
We can not put private,protected, internal protected over
the classes.. it is public by default...
The main purpose of putting "sealed" for the classes is to
prevent the other classes to refer it.It's functionality
can not be shared..
The important point is , "sealed" class can inherit from
any other non-sealed classes.. But no other classes can
inherit from a sealed class..

Answer / guest
the diffenence between the TWO is that:
In private Class: We can create a constructor and therefore
we can create an instance of that class.
But
In Sealed class we can not create a constructor of that
class, so no instance of that class is possible.
Private Constructor of a Private Class = Sealed Class.
