Arrays in Kotlin

The entries of lists are mutable and can be changed freely, using indices and the index operator []:

The index operator [] takes an index and a value and changes the element placed at that index with the argument value:

val numbers = mutableListOf(50, 40, 30)

numbers[0] = 15
numbers[2] = -1

// numbers is now [15, 40, -1]
