Kotlin Standard Delegates - Lazy, Observable and Vetoable

This is the final video about Kotlin Delegates. So far we have learned about Delegation Pattern, we also learned how it is super easy to make delegation in Kotlin as it supports it natively. And we also created some Delegates.
In this video we will learn about the Delegates that are predefined in Kotlin Standard Library.

At 4:52 I accidentally said that "to the constructor we will pass", but the observable is a function and not a class. So here we are passing the initial value to the function as a parameter. Sorry for this.

These are awesome do you videos explaining all about lamdas. It's hard to understand :(

[@gibraanjafar1669]

If incase anyone is using some other editor like VSCode, vim etc , do add the import => import kotlin.properties.Delegates.

[@brucebane7401]

what is the datatype/classtype of heavy. dont we have to specify a classname when lazy loaded like
val heavy:Classname by lazy ......

[@akashviet007]

we can observe the changes by defining normal setter also, then what is the use of Delegate.observable ??

[@SimplifiedCoding]

Functionality wise both are same but delegates may be better in cases where you are having the same functionality for multiple variables.
With setters you need to write duplicate code
but
You can assign the deligate to a variable and then use the same variable as the delegates. This will reduce your code repetition.

Hai bro, why video quality is only 320p what happened?

[@SimplifiedCoding]

UA-cam takes some time to process HD videos, after some time it will become Full HD.

@@SimplifiedCoding i seen in 1440p60 thankyou so much sir for all your helpfull videos

[@arjundixit5913]

vetoable vs setter? set(value) { field = value } also does the same thing i guess

[@vathsan3906]

I guess vetoable is like set(value) { if(condition) field = value }
