Scala Map Programs

In Scala programming language, a map is a collection of key-value pairs. A key is always unique while values can be different. Maps are classified into two types: mutable maps and immutable maps.
By default, maps are immutable in Scala. To use a mutable map – we have to import scala.collection.mutable.Map class.

This section contains solved Scala map programs, practice these Scala programs to learn the concept of Scala maps, these programs contain the solved code, outputs, and the detailed explanation of the statements, functions used in the Scala map programs.
