Kotlin Delegating Properties Tutorial with Example

[@RCMOULI1]

Kind of confusing syntax but explained well. Programming is getting crazy over the decades.

[@ahmednabil5119]

Finally, I understand delegation. THANKS ALOT.

[@Talhaguy]

Beautifully explained, thanks!

[@SimplifiedCoding]

Thanks ❤️

[@VenewebTV]

Excellent example, regards from Caracas, Venezuela

[@udaysharma5228]

Amazing explanation. I never thought how easy it is.

[@this-is-bioman]

Excellent! I finally get the idea and I love this feature ;-D

[@lucycat-p2l]

Best explanation, thanks a lot

[@zet_indexx10]

We can also use "data class" for printing the class :)

[@preethivalsalan839]

you have explained very well

[@bharathanddata]

is NameDelegate object created for each property or there is only one object for every property. Because if it create objects for each property then it may be inefficient.

[@alvaroisea2259]

Thanks a lot, such a clear explanation

Hi belal... Can you please make just one more video on reflection in kotlin and add it to this list,,,, I need to fully understand Reflection,, you are amazing teacher thank you

[@namrathabharadwaj8945]

Hey Belal. How is this delegation any different than creating a common private method to avoid redundant code? I mean what is the significance of delegation over creating a common method in this case?

[@SimplifiedCoding]

Can you submit your version of the code?

[@jasdevsingh6795]

Can't we achieve the same with extension functions ?

[@ss-xn5rw]

you explained this very beautifully

[@oparvind]

Thank you Sir

[@junigates]

confusing with operator fun , by the way great info

[@vidyesh]

Custom implementation of the 'setValue' operator using operator overloading.

[@kishorramani007]

Hi
Have one doubt
I try to re assign some different value (which is below range of 5) in student's firstName and lastName but it cannot assign again
In output, it shows old value

[@ravipratapsingh3428]

How I want check varriavble value is even only using a single variable not a class

[@shreyashchoudhary7413]

Loved it!

[@arjundixit5913]

Okay I understand delegation, but what would be called as delegate in the above example?

[@deepakbisht4957]

It is delegation in the sense that you are sending validation responsibility to another class that actually validating the first and last name.

[@Saranshhanda]

thanks man!

[@master8994]

I didn't understand the property thing please someone explain

[@shashankrana977]

Viradar you threw Kproperty and operator keyword without explaining, I finding it difficult to follow this way

[@avishekthapa6655]

cant we just create a function that does the validation and used that validation in setter and getter like this
class Student {
var firstName: String? = null
set(value) {
if (isValid(value))
field = value?.trim()?.toUpperCase()
}
var secondName: String? = null
set(value) {
if (isValid(value))
field = value?.trim()?.toUpperCase()
}
private fun isValid(data: String?) = data != null && data.length > 5
}

[@SimplifiedCoding]

Still the delegation is more concise as you can clearly see.

Hi sir , how to crack technical round android interviews 😢
Suppose if they ask either API calling or something like that?? I am new...

[@ss-xn5rw]

you can say i am fresher and learning these topics or better to learn these topics in this channel.

[@praveennp4108]

@@ss-xn5rw thank you...😊😊

[@amitrajj]

This can be done easily by using Extension functions.
