Answer / nevin jain

yes off-course instance can be created...

just make a static function say ReturnInstance() within the
class n keep return type of this function as the name of the
class..
with in ReturnInstance() method return the object of the class..
As the method is static so it will load without using
instance n now we can assign the object(or instance)to the
variable of class type...

examine:

public class A
{
private A()
Console.Writeline("Instance is created");

public static A ReturnInstance()
{
return new A();
}
public void Display()
{
Console.WriteLine("Display is accessed");
}
}

class MyMain
{
public static void main()
{
A a=A.ReturnInstance();
a.Display();

}
}

Answer / ranjeet saini

it does not throw an exception
bcoz we can create private constructor if we have static member in class
in this we can create a reference object with the help of static method.
class A
{
private A()
{
C.w.l(" Hi");
}
public static display()
{
return new A();
}
S V M ( S[] args)
{
A a=a.display()
}

}
