Arrays in Kotlin

Arrays in Kotlin in Few Words

Arrays in Kotlin in Details

[[Arrays in Kotlin]] are invariant, this means that the [[Type]] cannot be changed.

If we want to have dynamic array [[Type|types]] then we should use a [[Generics]], more precisely [[Generics in Kotlin#Type Projections|Type Projections]].

Build an Array

With a [[Constructor]]

val tab = Array<Type>(size) { values}

With a [[Factory]]¹

val tab = arrayOf(val1, val2,  ...)

Access An Item

tab.get(indexOfDesiredItem)
tab[indexOfDesiredItem]

Primitive Type Arrays
