Comment on Why do I need inheritance in OOP? Real-world examples. by Prashant

What you have shown in your blog is a way to implement inheritance.In my view inheritance is concept where one brand new object use some or all property of another object i.e. reuse the property of existing object rather than creating new.

Some Real World Example:
Battery and charger of Mobile Phones and Mobile of Nokia-Battery and charger is made ones and being used in different different models of Nokia mobile phones.

Pencil Battery-an object——>used in radio,torch,toys.Etc(i.e. reuse of existing object in another object)Companies which are making torch,radio,toy they are just using the battery rather to make a new battery.

Thanks

what is missing in your example, and what is on the main reasons to have polymorphism in the first place is this class:

public class PetTrainer {
public void makeMyPetTalk(Pet p) {
p.say();
}
}

As you can see, PetTrainer can make any Pet talk – cats, dogs or even tigers that might come in the future.

Awaisdar:
The reason why the same code won’t work without correction in C# is the following:
in Java all methods are virtual by default, compare to C# where in order to make them virtual you have to specify “virtual” keyword. The following program is C# version of the example code:

using System;

namespace Test
{
public class Pet {
public virtual void say() { }
}

public class Dog : Pet {
public override void say() { Console.WriteLine(“I am a dog.”); }
}

public class Cat : Pet {
public override void say() { Console.WriteLine(“I am a cat.”); }
}

class Program
{
static void Main(string[] args)
{
Pet pet1 = new Dog();
Pet pet2 = new Cat();
pet1.say();
pet2.say();
Console.ReadKey();
}
}
}

in c# after
Pet pet1 = new Dog();
cat pet22 = new cat();
when i called
pet1.say();// it shows the say method of Pet class not of dog class.
and pent22.say();//shows the Cat class’s say method.

???????????????????

Comment on Facebook’s most annoying issues 2 by Vlad Z (AX guy from Kharkov)

You’re right Artem, now it’s being a couple of months already and I don’t see much improvements since (maybe Facebook via Skype access but Skype itself has some annoying new “features”:)

And so often these people responsible for feedback to R&D who read (and answer!) “flame” blogs often don’t seem to react with product updates.

Personally I really like Google in how quickly it adapts to the users needs.

I was skimming through the comments people say and, in fact, this is a quite good and simple example of why to use so-called Liskov principle. You can always generally call Pet->say() via Pet base-class pointer not caring what subclass it actually represents (Dog, Cat or Bird). This is good and right practice in OOP.
