Kotlin Generics Explained with Example

In this video "Kotlin Generics Explained" we will learn about generics in Kotlin. Generic is a powerful feature of any object oriented programming and using it we can define classes or functions that can work with different data types.

For the first time, I really understand generics. Thanks a lot

[@janadonis5211]

What a great teacher! keep up the good work, thanks a lot man!

[@nishu33389]

Thanks Belal for the kotlin tutorial series 😃🙏

[@DSW2022]

You are a brilliant teacher Bilal. Thanks to you now I understand generics.

[@kevgits]

I couldn't understand this concept even after going through the docs. Thank you for this simplified version.

[@vengateshm2122]

Add a video on covariance, contrravariance, invariant.

[@Sumitmaurya070]

very good feature of kotlin. Thanks for the info,

[@GriNAME]

Thank you so much! Your vidios are so useful for me (and for other I guess). You made my coding live more better, I mean it! With love from Russian 💪👍

[@techmarinar]

Thanx man this was very helpful 😊

[@kpranjith]

wow great explanation with example!!! 😍

[@shreyashchoudhary7413]

Loved it!

[@gilong1311]

Great video, do you have a video on usage of covariance and contravariance?

[@decloudius]

I don't know how to tell you my gratitude but, I love you sir, thank you

[@jkeriatamboli2101]

As in java for we compair int value using == like 1==1 but for string we compair using equals() like str1.equals(str2) so in kotlin for string == work

Thank you master

How to upload .db file (Of SQLite Database) to user's Google Drive?, in Kotlin?

[@positive_vibes_alone]

How can we achieve the same using pojo class as T ?

[@kristianabrahamsen7019]

good explanations!

[@IUfidi]

I like ur style!

[@johndominicjasmin]

Thank you

[@user-nh9ih4mj8i]

good examples

[@MisterWealth]

Are generics for beginners intermediate or pros? Because this seems like a difficult concept to grasp for me :(

[@milon27]

When to use & when only

[@SimplifiedCoding]

In very simple words
When you make your T out you can only define it as return type in function if you try to write it as a parameter you will get error.

@@SimplifiedCoding thanks

[@vengateshm2122]

Can we use Any instead T ?
Because Any is the class which is extended by all classes in default?

[@SimplifiedCoding]

When you write T or any character; it basically means any. Here you cannot define the actual type not even any.
Any is there by default. It means T : Any that is you can define any type that inherits Any and Any is the super type of all classes.
You can also restrict by defining a specific parent for example T : View
It means here for T we can define any type that is a View.
So you cannot write the class name here. But you can define a super type if required.
