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

Thanks RadhaKrishna

Kati arulai dukh din janeko yo cp21 le, Google gareko bhaye bhai halthyo ni. Ma pani stupid nai ho yo comment lekhera time waste gardai chu as Radhakrishna wasted his time to google it for you and pasted it here.

I'm simply asking to get better understanding from working professionals. Is this not a legitimate question? Do I need to ask for your permission prior to posting a question which is absolutely and completely valid within the realm of computer and IT forum? Seriously, stop making smart ass comments and continue to scroll through page.

Incompetent idiot without a life, go find something better to do with your life...

Wow, hera na yo cp21 lai kati ris uthya?? Tero gali khanu raixa, dinai bigaris mero!!

hahaha.. nice Pharsi...!!! tara pani Chandra Prakash bhai, risaai haalnu parne kehi thiena, ani gaali garnu, ya mukh 6aadnu ta pattakkai euta professional lai suwaaudaina... say sorry to Pharsi, if you really care about the suggestion we give, and if you are really an aspiring professional in the field of IT...

WTF is wrong with these idiots. The purpose of this forum is to post questions regarding computer and IT.

Seriously, are y'all like going through the stage of mental retardation or just born dumb?

Tero bau ko ta kei khaideko chaina. kina yo forum ma ayera mero bheja khanchass

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!
