12.3 Object Serialization in java | Serializable Interface

[@RaviKumar-n8k6g]

the way of teaching via is code is really understandable more than read a theory in 30 minutes,thanks i will continue to watch ur videos..

[@amanmishra98apr]

Very useful lecture for me...Thank you sir, I'm following you from 3 years.

[@brunofilgueiras3518]

man, thanks for this material, the way you explained, the sequence of each idea was just perfect.

[@Govindyatnalkar]

You and Durga sir are wizards in JAVA!!!

[@pulkitkaushik4539]

Java Brains wants to know your location

[@nehamakeovers4704]

At 2:15, you mentioned, Save obj1 = obj will create a copy of obj. It's not correct. obj2 will point to the same object as obj, it is just a reference; no copying occurs here.

[@dskundan]

Excellent Example, just Legend!

[@spiritualquest6092]

Super explanation, thanks for your time!

[@foodfairyshi]

best explanation. Thank you

[@bharatmakkar9706]

Simple + effective

[@NexGenSlayer]

You shouldn't keep saying the "NULL" object has a value of zero -- it is simply null. There is a big difference in these two things.

[@walkerscoral]

Yes thank you CS 101

[@higiniofuentes2551]

Thank you for this very useful video!

[@A_Dark_Knight]

you r my best teacher

[@damodaranm3044]

such a badass explaination

[@slobodantajisic2762]

It is strongly recommended that all serializable classes explicitly declare serialVersionUID values, since the default serialVersionUID computation is highly sensitive to class details that may vary depending on compiler implementations, and can thus result in unexpected InvalidClassExceptions during deserialization...

[@animesubber7136]

how to do so?

[@animesubber7136]

private static final long serialVersionUID = 4L; insinde the class with implements serialization

[@mekings0422]

This is an amazing tutorial, exactly what I was looking for... thanks a lot bro

[@kushalupreti509]

You are a god.

[@TheSubhadipMondal]

Thank you... concept got cleared

[@ultimatehuzefa]

The best✨

[@ayushyadav4180]

great tutorial man

[@muskandahiya6257]

He haven't closed the objectoutput stream

[@premkumar-jz4di]

super sir well explained

[@SirToniTheFirst]

Hi John, can you please make a video about serialization, I don't understand a thing about it and the tutorials on youtube are hard to understand, they're old too. I hope you see this, thanks a lot, you've helped me a lot in java

[@natsnettesfamariam7868]

Thank you Telusko. You are really good teacher. I always see your tutorials. in this example are we saving the object over a network???????

[@SivaNagaSureshKatarii]

Not exactly, Here we are saving the object in a text file(Serializing). After saving the file, you can transfer the file (containing our object) over network. After receiving the file from the other end of network, we can read the object(De-Serialize) from the received file. In this particular scenario, both serialization and de-serialization are done in the same machine(without our network step involved).

[@adilsaju]

Awesome video man. Keep it up.

[@ShivamKendre-fc3su]

great video

[@vladanulardzic5859]

Well done ! Keep on.

[@hwangclara4024]

Can you please explain Serialization with static variables and transient? It will be better.

[@fatimaadreeta]

great video. I just wanted to ask what is the difference between ObjectOutputStream and DataOutputStream?

[@mohammedviso2269]

Great tutorial.......Thanks

[@clawciita]

great video! just what I was looking for

[@slonbeskonechen8310]

Awesome!!! Thank you!

[@akhileshagrhari924]

Thank you Telusko for the amazing explanation. I just got a doubt while watching this video. What is the difference between saving objects and saving data? I'm curious to know the difference between data and objects.

[@becomingbless]

How do I find the previous video? 🥺

[@saikrishnamanchikatla7677]

does memory is created for obj1 in heap when we say Save obj1 = (Save) ois.readObject();

[@tarankaranth8782]

excellent sessio. one question, will object code also get serialized and deserialized or only variable values?

[@yogeshthakur535]

Sir in mine.. i can't see my saved file obj.txt.. Actually I searched it. But file is not saved

[@cristianmanolachi3771]

Hello i did a game in gameguru but i can*t save it.How can i do a savegame file becasue there are not a fucntion to save the file

[@abddesd1492]

can we you any marker interface interchangable ,for example instead of serializable can we use clonable interface is it posssible

[@ramadevivakkalanka2998]

Nice workdone .. Thank you...

[@wanderwithpumpkin185]

Thank you

[@datsonyan3499]

nicely explained.

[@sahilkhotkar3574]

Thanks,helped a lot

[@addagadavenubabu2558]

Can you please explain about serialization version id it will be better.

[@MadForCs16]

nice and simple.

[@HareKrishna15]

Thanks dude

[@chandhrum9061]

Why a dto needs to be serialized??

[@mr.RAND5584]

Is that sir updatable? Like mysql, excel , word ?

[@rakshitks7850]

Exception in thread "main" java.lang.ClassCastException: java.base/java.lang.String cannot be cast to rak at Main.main(Main.java:23) help me out with @Telusko Learning

[@JR-mk6ow]

You simply can't convert a string directly to Tak object. Try to implement the toString() in the Rak class

[@SyedMuhammadAli-tr4cg]

where is serialization used other than file handling

[@SyedMuhammadAli-tr4cg]

where

[@yogeshpatole9595]

Why r u change in fos to oos

[@dolevdo]

amazing

[@prelimsiscoming]

Why (save) is needed?

[@dominicxavier5274]

what is the diff b/w object serialization and object cloning?

[@harigoutham7651]

dominic xavier Object cloning is creating a copy of an object and you don't store it and use right way in the code . Object serialisation is copying and also storing object ( may be in a file or database or over a network ) and then you can retrieve at later point of time . It is not possible in case of cloning

[@anshuyadav248]

program show unexpected output like "serialdemo@e9e54ce",serialdemo is name of my serializable class

[@vladeb1104]

chyba sam zaczne robić tutoriale, nie wyrabiam już z tym akcentem

[@aidandanielski]

Don't you have to close these files?

[@m3r5]

Obj1=obj will not copy the values It will copy the reference of obj into obj1 Clear your concepts first

yeah bro exactly !!!

[@harshverm776]

This time you haven't explain- why we need it ? What are is uses ?

[@manavmalhotra8513]

Why typevasting in save?

[@nithyashreenaidu8357]

you are explicitly converting it

[@yousraahmedd]

Thankss!!

[@neomillmarcreas6535]

The explanation is vague

[@doplerfish]

Thank you!

[@ragavendravignesh1028]

The default value for an object is null. But you are mentioning it as 0

[@_jamesbro_]

Integer default is null int default is 0

[@prim16]

Thank youuuuuuuuu

[@veerakondratenko1160]

Need to work on accent perhaps. Too fast explanation. Hard to understand words.

[@zbigniew463]

I know that you love sound of your voice, but you do the presentation for me, so get to the point, and skip the hay.

So many mistakes in 4 minutes :(

Cant understand

[@philipvarghese2863]

+Anshu Yadav I know its too late, anyway when you simply try to display an object it will be in the format "type@address" to represent the object in string we have to override the toString method of Object class. In this case the toString method will be as follow.. @Override public String toString() { return "Save [i=" + i + "]"; } Note: it should be implemented in the class Save
