How to create an integer array using the int keyword in Scala
Theodore Kelechukwu OnyejiakuOverview
In Scala, we can easily create an array of integers using the new keyword. We need to call the new keyword to create an array.
Syntax
var ArrayVariable = new Array[Int](numberOfElements)
Syntax for creating an integer array using new keyword
Parameters
ArrayVariable: This is the array variable that will be initialised with some elements.Int: This parameter specifies that the array must be of type integer.numberOfElements: This is the number of elements in an array.
Return value
We use the new keyword to convert the array variable to an array instance. We use the int to specify type integer. This means that any of its elements must be an integer.
Example
object Main extends App {
// create array of integers with "new" keyword
var OurArray = new Array[Int](3);
OurArray(0) = 10;
OurArray(1) = 3;
OurArray(2) = 1;
// print out array values separated by commas
println(OurArray.mkString(","));
}Creating an array with the new keyword in Scala
Explanation
- line 3–6: We create an array called
ourArrayby using the keywordnew. - line 9: We use the
mkString()method to print the elements of the array in form of a string separated by commas.
