How to create multi-dimensional array in Scala

Answer 1

val rows = 2
val cols = 3
val arr2d = Array.ofDim[String](rows, cols)

// row 0 (1)
arr2d(0)(0) = "Arthur"
arr2d(0)(1) = "Albus"
arr2d(0)(2) = "Alia"

// row 1 (2)
arr2d(1)(0) = "Artemis"
arr2d(1)(1) = "Deckard"
arr2d(1)(2) = "Dana"

for (i <- 0 until rows; j <- 0 until cols) {
  println(s"($i)($j) = ${arr2d(i)(j)}")
}


 
/*
run:

(0)(0) = Arthur
(0)(1) = Albus
(0)(2) = Alia
(1)(0) = Artemis
(1)(1) = Deckard
(1)(2) = Dana
