We used to create our own pair classes to use in project. Now it's cool to have ready to use libs. Thank Techie

[manoganesan]

I have implemented this concept in one of our existing methods after watching your video. You are awesome!

[gopisambasivarao]

Appreciate your efforts Basant! God Bless you!🙏👍

Thanks buddy. Every time i got a notification from you , got curious to learn new thing to build my carrier growth.

Return a list of POJOs. Another way to implement this. Like in all languages, different ways to perform such tasks.

Thank You Basant Bhai, I was not aware about these fantastic classes. Thank you for sharing it, now I will try to use this in my project.

Please do not use this, the readability is so much lower. Multiple return values are a sign of too much responsibility or a lack of domain understanding. We create on purpose objects that hold values to communicate intend or coupling.
In Go we use them to return value, error that is a totally different approach.

Thanks sir to share this knowledge 🙏, even though i used Pair class many times in my code.

[El_Espada]

Kotlin has this feature and I find it awesome.

[raghavanaliassaravananm]

Interesting Video. Thanks for sharing Basant.

[saravanasathish]

This common lang3 will reduce writing multiple methods, thanks for the info ❤

[rudrajitgupta]

This was awesome Basant..thank you for the learnings

[MrKKPA]

What might be the benefits of adding a library to do that when you can achieve the same by creating a object that contains the others nested objects?

[saim]

Please do the video on remove duplicates in custom objects by using key using java stream api.

Your videos are so boosting up my skills a lot.Thank you so much

[bugra]

I believe it is better to create a Dto class that contains those two objects and return the Dto object

[samsneera]

How will this be useful if the number of objects to be returned are more than three?
Considering readability and convenience, this feature looks good. As per my understanding, we can come up with our custom class containing these multiple records to be returned.

[MurariKumar-wptd]

Thanks.. it is very useful for developers ❤👍

[Nilcha-]

Though this makes it more object oriented, in the old days I use pass such object by reference to the method arguments. You can send back more than 3. Only it is mutable and open to side effects.

[maheshwer]

We can use pojo class instead, which would be more cleaner and easy to understand approach, this approach creates confusion for new devs

Hi Basant, I need some suggestion regarding one of the requirement.
I need to reterieve the data one of the database table, it has morethan 3 lakhs records (for first time), 1. I need to call some 3rd party API for each rows and get some relavent details from API resonse and then I need to update same row with other 2 fields. So how we can handle entire thing in same request and wtih in same end point. (bascially retreive data, do same change in row, update same row for those many records).
2. This can be run on weekly batch. ( may be first time 3lakh records, later batch run it might be less), based on flag in DB column we can identify allread processed or not processed rows.
