Inheritance Advantages and Disadvantages

Advantages:-

One of the key benefits of inheritance is to minimize the amount of duplicate code in an application by sharing common code amongst several subclasses. Where equivalent code exists in two related classes, the hierarchy can usually be refactored to move the common code up to a mutual superclass. This also tends to result in a better organization of code and smaller, simpler compilation units.

Inheritance can also make application code more flexible to change because classes that inherit from a common superclass can be used interchangeably. If the return type of a method is superclass

Reusability -- facility to use public methods of base class without rewriting the same
Extensibility -- extending the base class logic as per business logic of the derived class
Data hiding -- base class can decide to keep some data private so that it cannot be altered by the derived class

Overriding--With inheritance, we will be able to override the methods of the base class so that meaningful implementation of the base class method can be designed in the derived class.

Disadvantages:-

1.One of the main disadvantages of inheritance in Java (the same in other object-oriented languages) is the increased time/effort it takes the program to jump through all the levels of overloaded classes. If a given class has ten levels of abstraction above it, then it will essentially take ten jumps to run through a function defined in each of those classes

2.Main disadvantage of using inheritance is that the two classes (base and inherited class) get tightly coupled.
This means one cannot be used independent of each other.

3. Also with time, during maintenance adding new features both base as well as derived classes are required to be changed. If a method signature is changed then we will be affected in both cases (inheritance & composition)

4. If a method is deleted in the "super class" or aggregate, then we will have to re-factor in case of using that method.Here things can get a bit complicated in case of inheritance because our programs will still compile, but the methods of the subclass will no longer be overriding superclass methods. These methods will become independent methods in their own right.


Inheritance offers the following advantages --
Developement model closer to real life object model with hierarchical relationships
Reusability -- facility to use public methods of base class without rewriting the same
Extensibility -- extending the base class logic as per business logic of the derived class
Data hiding -- base class can decide to keep some data private so that it cannot be altered by the derived class

hey cp21,
You have shown that what level you belong to. Ma gaye jati gali garnu xa gara.

cp21, People are trying to help you out but you are proving yourself an idiot with your comments. Bro, you need to put an effort from your side as well to learn CS concepts and programming. The way you are asking simple questions without enough studying is just irritating. And, this is coming from a CS student myself . It will be on your benefit if you study the material first and may be watch some youtube videos.

Does it hurt anyone if I POST a FUKING QUESTION?

If you don't want to respond, then mind your FUkING business.... Whoa these idiots keep piling up... OMG what is up with these idiots... I have done all my studying as, but I want people to share their perspective on given topic.

@ cp21:

Yes CP21, an idiot see everyone an idiot because he thinks he is the smartest person in the planet. So it makes sense to us when you time and again tells everyone of us idiot. And it is because you are the biggest dumb ass, idiot in this whole planet. Put your ass in the library and study.
Yes, you are nobody's bro because you do not deserve to be anyone's bro. You are just that cheap ass retarded bastard son of your mother who even does not who your father is so far.
This forum is not the property of yours... so make it clear and understandable that if you post any such stupid, lazy ass questions, you will get a backlash.
Now, be a quite kid! and go home and ask your mother who your father is... that you need to find first. Once you know who your father is, ask him to whip you ass. you need some manners, kid!
Also, stop using this site, this site is not for the person like you who misuse it. Moreover, it is NOT for kids like you.

I feel sorry that your mother dropped you on your head when you were just 9 months old. Hence, a retarted little fuker who continues to lurk around this thread.

If you reply back then its a fact that you were dropped during birth.

@ cp21:

Since you started attacking an individual's character and personality, I am not going to leave you like this. You will get responses on every post you publish. Will try to always divert the topic you posted unless and until you SHUT your mouth up, util, you really start putting your ass on study, until you correct your mistakes and apologize to all publicly (Which I know you will never do. Coz, you do not have the guts, coz you are not a human).
You are the son of your whore momma who still is searching his father

I rest my case!!! Poor little boy with his itty bitty microscopic penis.

@ cp21:

Ask your mother whose disk is microscopic...?? She will tell you about mine too... coz she really enjoyed that in her ass....

@cp21,
First of all, I am sorry if I initiated your anger. All I wanted to tell you was to put some efforts into it before you ask general questions whose answers can simply be found. If you don't find the solutions, then ask professionals so that we could find the solution together. Thats all I wanted to say.
@ Radhakrishna
Sorry Dai for initiating all this shits. I didn't mean it but it happened. Just chill chill!!

It is fine Pharsi.

This cp21 is just a piece of shit and fool. He needs to learn how to talk. Does not have any manner or respect for anyone. The person who does not respect others does not respect himself as well. He really needs medical help because he thinks he knows all and he can just bully anyone when somebody reacts to his dumb and lazy ass questions. It is absolutely not fair.

Well, I do not act like this mostly, I am not rude and inappropriate person, I apologize for all the rudeness and nonsense I am talking which might be offending/insulting to most of us...

BUT SOMEBODY TOLD ME THAT TO TEACH A FOOL A LESSON, YOU MUST ACT AS A FOOL YOURSELF... Because a fool only understand his own language, that is fool's language.

@RadhaKrishna
“Never argue with an idiot. They will only bring you down to their level and beat you with experience.”

I don't even know why you bother to copy paste from google and answer which he could have easily done.. just ignore bro!

Cp21,
Can I tell you something? Calm yourself down and listen to me. I was the one who initiated all the fights here so you can say anything to me. But, Radhkrishna genuinely helped you and you are giving him all this in return. I strongly believe that this isn't right and appropriate, and you owe an apology to Radhakrishna.

Radhakrisn: I know you would like to give a genuine advise and easiest thing is to advise. And very few people take it seriously , rest will see it negatively and may take it is as a parental advise. 
I see a lot new thread because of your advise?

magorkhe1, the new threads are because of cp21's ego, immaturity and anger management issues.

Radhakrishna and Pharsi, it's not worth arguing with chandra prakash. So, ignore him and have a nice weekend.

@ magorke1:

It is fine buddy... I can understand what you are saying. Most probably you did not get from where it begin. It is not today's story alone.
This little bastard cp21, who is a nepali, says that he does not know nepali... and starts abusing genuine person who helps him with his stupid lazy ass questions which he can easily find googling it. And when somebody says him something, he starts abusing that person. And he has been doing that for a long time.
He thinks that he is studying in IT field, most probably would always call him as an ENGINEER, but in reality is sucking cheap ass dhoti's dick in a consultancy and shows the manner of a cheap ass third class individual by abusing and disrespecting all.
Enough is enough for this bastard child.
Whatever advice it is, we are not telling him how to live his damn retarded fucking life. We are just asking him to pay some respect and have some manners.
But it is just an another day to him, I know that. Few days back, he was fighting with somebody else, today he started bullshitting with me and tomorrow, you may the person, who know.
Thanks for your advice though. Will keep in mind.

cp21 should have some respect to people who genuinely help others in sajha, like Mr. RadhaKrisha. No body is paying anyone for help or their valuable time giving suggestions. It's for free and comes only because we Nepalis have lots of empathy and at one time we all have been through the same situations. cp21 should have respect for RadhaKrishna ji. He has genuinely helped lots of people in sajha and always give honest answers. If he's telling you to study you should take it as a suggestion from a big brother and maybe in your best interest to do so.

CP भाई , गूगल मा एउटा click गरेर पाइने उत्तर लाइ तिमि ले येहा पोस्ट गरेउ तै पनि अरु ले उत्तर दिए | धन्यबाद दिन त कता हो कता हो उल्टो गालि गर्न मा उत्र्रेउ ! लाज लाग्दैन भाई ?
*भाई किन भनेको भन्लाउ , तिम्रो बोलि चाली कुरो गरे को ताल हेरेर दाइ त के मित्र नि भन्न मन लागेन !

Hey Chandra Prakash - Fuck You.
