whats the difference between these two ways of instantiating a string?

[joeykaan]

stringy2 actually has the type of optional string right, while stringy1 is a String, so it would make working with the stringy1 easier

[Rob Murdock]

The first variable will infer its type, which will be “String” (aka the non-nullable version)

The second has to have it declared, and because the type is String?, will require null checks in order to use

ohh okay thats not what i was expected, i was actually asking in regards to when/how they are instantiated. like, are they done at the same time? i know java doesnt have the init method as far as im aware so im just curious what it does/when i should be concerned with it

[gian]

They are instantiated in order of appearance

[joeykaan]

If you're using Android Studio (which I assume you are) if you go to Tools > Kotlin > Show Kotlin Bytecode and then check the IR checkbox and then Decompile again

[joeykaan]

You can see the java code that is generated 🙂, that might help you to see the difference (if any)

[Tim]

oh sick! thank you

You can also make stringy2 not nullable and initialize it in the init block

Java has initializers, which can be static or not.
The non static ones are pretty much the same as kotlin's init afaik.
