THE SEALED KEYWORD

This key word is used to prevent any class from inheriting. So if we want to fix a condition that no class should inherit from this class, then we can mention that class as sealed class.

public sealed class demo
{
public int a = 10;
public int b = 2;
public void add()
{
int c = a + b;
Console.WriteLine(c);
}
}
Now I cant inherit this class 'SINCE IT CONTAINS A KEY WORD SEALED'.
