How can you prevent classes to be inherited?
Answer Posted / asit nutiyal(birla)
sealed modifier is used for preventing the accident
inhritance of a class. A sealed class can not be inhrited.
Example :
using system;
sealed class abc
{
protected string str = "";
public virtual void hello()
{
str = " Hi i am not in C#";
}
class xyz : abc //--ERROR--
{
public override void hell0()
{
str = "hi i am in C#";
Console.WriteLine("{0}",str);
}
}
class mainclass
{
public static void Main()
{
xyz x = new xyz();
x.hello();
}
}
Note-> if we run above program thn we will get an error
because we inheit class abc while it is sealed.
