No Scala mutable list

Question

Scala has both a mutable and an immutable Map , but it has only an immutable List. If you want a mutable List you need a ListBuffer.

I don't understand why this is so. Any one knows?.

Answer 1

You can choose between these:

• scala.collection.mutable.DoubleLinkedList
• scala.collection.mutable.LinkedList
• scala.collection.mutable.ListBuffer
• scala.collection.mutable.MutableList

So, yes, Scala has mutable lists :-)

Answer 2

I hope that this article may be of some use to you. The diagram at the bottom of the page is particularly useful in providing the mutable and immutable classes.
