Hey,

ofDim() is a method in Scala that lets us create multidimensional arrays. Since these let us store data in more than one dimension, we can store data like in a matrix. Let’s take an example.

scala> import Array.ofDim

import Array.ofDim

scala> var a=ofDim[Int](3,3)

a: Array[Array[Int]] = Array(Array(0, 0, 0), Array(0, 0, 0), Array(0, 0, 0))

scala> var k=1

k: Int = 1

scala> for(i<-0 to 2){

| for(j<-0 to 2){

| a(i)(j)={i+k}

| k+=1

| }

| k-=1

| }

scala> a

The output will be like:

res12: Array[Array[Int]] = Array(Array(1, 2, 3), Array(4, 5, 6), Array(7, 8, 9))


Hope this helps!
