Scala Multidimensional Array

Multidimensional array is an array which store data in matrix form. You can create from two dimensional to three, four and many more dimensional array according to your need. Below we have mentioned array syntax. Scala provides an ofDim method to create multidimensional array.

Multidimensional Array Syntax

var arrayName = Array.ofDim[ArrayType](NoOfRows,NoOfColumns) or
var arrayName = Array(Array(element...), Array(element...), ...)

Scala Multidimensional Array Example by using ofDim

In This example, we have created array by using ofDim method.

class ArrayExample{
    var arr = Array.ofDim[Int](2,2)  		 // Creating multidimensional array
    arr(1)(0) = 15                     		// Assigning value
    def show(){
        for(i<- 0 to 1){             		  // Traversing elements by using loop
           for(j<- 0 to 1){
                print(" "+arr(i)(j))
            }
            println()
        }
        println("Third Element = "+ arr(1)(1))        // Accessing elements by using index
    }
}

object MainObject{
    def main(args:Array[String]){
        var a = new ArrayExample()
        a.show()                     
    }
}

Output:

0 0
15 0
Third Element = 0

Scala Multidimensional Array by using Array of Array

Apart from ofDim you can also create multidimensional array by using array of array. In this example, we have created multidimensional array by using array of array.

class ArrayExample{
    var arr = Array(Array(1,2,3,4,5), Array(6,7,8,9,10))   // Creating multidimensional array
    def show(){
        for(i<- 0 to 1){               // Traversing elements using loop
           for(j<- 0 to 4){
                print(" "+arr(i)(j))
            }
            println()
        }    
    }
}

object MainObject{
    def main(args:Array[String]){
        var a = new ArrayExample()
        a.show()                     
    }
}

Output:

1 2 3 4 5
 6 7 8 9 10

Scala Addition of Two Matrix Example

You can manipulate array elements in scala. Here, we are adding two array elements and storing result into third array.

class ArrayExample{
    var arr1 = Array(Array(1,2,3,4,5), Array(6,7,8,9,10))   // Creating multidimensional array
    var arr2 = Array(Array(1,2,3,4,5), Array(6,7,8,9,10))
    var arr3 = Array.ofDim[Int](2,5)
    def show(){
        for(i<- 0 to 1){               // Traversing elements using loop
           for(j<- 0 to 4){
                arr3(i)(j) = arr1(i)(j)+arr2(i)(j)
                print(" "+arr3(i)(j))
            }
            println()
        }    
    }
}

object MainObject{
    def main(args:Array[String]){
        var a = new ArrayExample()
        a.show()                     
    }
}

Output:

2 4 6 8 10
 12 14 16 18 20
