How to get the size of an array in Scala

Overview

We can get the size of an array using the size property. Array size is the number of elements that an array contains. It is similar to the length property.

Syntax

array.size
Syntax for size of an array in Scala

Return

The value returned is an integer value that represents the number of elements present in the array.

Code 

object Main extends App {
    // create some arrays
    val randomNumbers = Array(34, 2, 5, 70, 1)
    val fruits = Array("Pineapple", "Banana", "Orange")
    val cgpas : Array[Double] = Array(3.4, 4.5, 2.5, 0.5)
    // get and print there sizes
    println(randomNumbers.size)
    println(fruits.size)
    println(cgpas.size)
}

Explanation

  • Lines 3–5: We create some arrays in Scala and initialize them with some values.
  • Lines 8–10: We get the size of the arrays using the size property. We then print the values to the console.
