So, this is similar to FIFO(First In First Out) principle. If we want to de-serialize rat object, we have to 1st deserialize the dog and cat objects. This is inefficient. because, the dog and cat object will occupy jvm heap memory. If there are 100 objects deserialized, it may cause memory Exception. Also in linux, the max file size is 2GB. we cannot write say 1 million objects into that 2GB file right ? how is this limit constraint taken care.

I don't generally appreciate everyone.... But this guy is the best Try explain and teach like him... Need 🦍 gorilla balls for that Don't ridicule his language proficiency

[@SivaKumar-cx7db]

People are keep working in java for 10 years or so.... I am sure, no one can have this much knowledge on internal things...

[@gautamkanawade3156]

Sir you nicely explained that how to serialize and deserialize multiple objects. I am having one doubt that if i don't know the number objects serialized in specific file then how could i decide the number of iterations of loop to deserialize those objects?

[@jayantagarwal6339]

12:06 - it was able to de-serialize only the first object, i.e. the Dog object, but not the second one, Sir.

[@shefaliarora4992]

hi sir, your videos are awesome. i tried serialisation of static variables. They should be skipped, but when I am deserializing from the file, it is printing the static variable as well. Why is this happening?

[@shankars4281]

Static variables doesn't take part in serialization, since serialization is for objects. And static means, its not related to object. So, its value will remain unchanged. Its not printing the value from file, when we serialize.

[@raman-jn6yt]

amazing !!!

[@AruneshSrivastava]

i dint get one thing...he said ..if we have lot of objects .. we ca put all in a loop and check it..but hoe ..beause ois.read() will only return one object at a time ?

[@horriblecoder7280]

and that statement will be under loop

[@ajeethkumarkandasamy5305]

while(fileInputSteam.available()>0) { object=ois.readObject(); //use this for loop for multiple object }
