sorry, i posted in wrong group before so only asked the question in #general

[rajendhiraneasu]

can you please explain the shallow and deep copy in kotlin? i can manage to get data class it works fine for deep copy... but i'm not sure about the shallow copy

[karelpeeters]

Are you sure that data classes do a deep copy? Do you know the difference?

[rajendhiraneasu]

data class Company(var TIN:String, var Size:Int){

}

var comp = Company(TIN="12345678910",Size = 100)

var compCpy = comp.copy(TIN="123");
comp.Size=90
println("Old Company $comp")

println("Copy Company $compCpy")

[rajendhiraneasu]

see here it does the deep copy only

[rajendhiraneasu]

oh okay got it

[karelpeeters]

When copying something with only immutable values (String, Int, ...) there's no difference.

ok
