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.

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.

For more details you can search Covariance, Invariance and Contravariance

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

[@Sumitmaurya070]

very good feature of kotlin. Thanks for the info,

[@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.

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

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