Feb 19, 2017 · Just a quick note today that if you want to create a mutable Scala array — particularly an array that can grow in size after you first declare it — you need to use the Scala ArrayBuffer class instead of the Array class, which can’t grow. Here’s a short example that shows how to instantiate an ArrayBuffer object, then add elements to it:

Mutable and Immutable Collections | Collections (Scala 2.8 ...
docs.scala-lang.org › overviews › collections
Scala collections systematically distinguish between mutable and immutable collections. A mutable collection can be updated or extended in place. This means you can change, add, or remove elements of a collection as a side effect. Immutable collections, by contrast, never change. You have still operations that simulate additions, removals, or updates, but those operations will in each case return a new collection and leave the old collection unchanged.

Array is a special kind of collection in Scala. On the one hand, Scala arrays correspond one-to-one to Java arrays. That is, a Scala array Array[Int] is represented as a Java int[], an Array[Double] is represented as a Java double[] and a Array[String] is represented as a Java String[]. But at the same time, Scala arrays offer much more than their Java analogues.
