How to Serialize Multiple and DIFFERENT Types of Objects in Java

Follow this tutorial along to learn Java Serialization for Multiple AND Different Types of Objects. We'll teach you how to write a whole bunch of different object and data types into the same file. Our example will write strings, integers, arrays of objects and arrays of arrays of objects, and then read them back in (deserialization).

The most helpful tutorial for this matter out of the many, many videos I've watched. Thank you!

This was by far one of the best tutorials I've seen it was complex enough to really provide and example but not overwhelm the viewer. I hope you keep uploading tutorials you are good at explaining and showing at the same time what you are doing.

How is that your channel is not so active? This is like one of the awesome videos that you can find on YT!

[Channel-iude]

This video has so much great information in addition to learning about serialization. Wish you'd make more.

Great combination of knowledge (Classes, arrays, arraylist plus serialization): a complex program made simple. Very useful for me. Great job!

[Bleilo]

This was really helpful and nice to watch. I liked the level of complexity and how you explained it, really well done!

[mimimalignant]

Absolutely well done!!! Not sure if it will help solve my issue, but well done is well done.

[kingmason]

Exactly what I was looking for! You are awesome!!!

Nice video. What if you want to modify the ArrayList element?

Hello, So i've been trying to make a program that reads each line of a file and store it into an ArrayList then serialize each line by line and save it. and load it & print everything as it has always been but I found a hard time doing it. Not gonna lie I'm kinda bad with ArrayLists aswell but what should I do ?

Hey guys,

I am creating a pizza delivery program in Java that uses a GUI. I was wondering if there is a way to save the current state of the application once I shut the system so when I start the application again I can start from where I left of?

For example if a pizza is getting delivered and I shut the application I want to be able to start the application and the delivery still being in the process of being delivered if that makes sense this would be displayed in a JTable i.e order ID, Delivered?
What would the best approach be for this? Would serializing be best for this?

Is there any way of doing this and if so can someone please explain or point me in the right direction.

Thank you

Hey Karleen, thanks for the tutorial.
It seems you have self humor,
so, it's perfect almost as an Indian tutorial ;)
I"m kidding
Blessings from HolyLand :)

First: Very good explanation of your work. I practice your tutorial and try to extend it. I try to write a file in append mode but I had trouble when I tried to read (deserialization). I can read only what I save (serialize) first time. Sure, exist a solution but I dont find. If possible help me !. Thank you
I used an ArrayList <class>
