Example # 1: Creating and Printing a List in Scala However, we will only be discussing the basics of using each of these collections over here i.e., creating a particular Scala collection and printing it on the terminal. Using the Different Collections in the Scala Programming Language in Ubuntu 20.04įor learning the usage of the different collections in the Scala programming language, you will have to understand the following four examples. Scala Tuple– It is a Scala collection containing a fixed number of items belonging to the same or different data types.The Scala maps can also be mutable or immutable. It means that the keys of a Scala map must be unique whereas there is no compulsion on the uniqueness of the values of a Scala map. Scala Map– It is a Scala collection that contains elements in the form of key-value pairs where the keys cannot be repeated.The Scala sets can be mutable or immutable. Scala Set– It is a Scala collection that contains pairwise different elements that belong to the same data type.Scala List– It is a Scala collection that contains elements belonging to the same data type.There are four main collections that are used most commonly in the Scala programming language and we are briefly going to discuss them below: Most Commonly Used Collections in the Scala Programming Language If you want to make a collection mutable, then you will have to import additional libraries whereas the immutable collections can be used as it is. The Scala programming language supports both mutable and immutable collections, however, by default, the collections in Scala are immutable. Mutable collections are the ones in which the contents of the reference can easily change, whereas immutable collections are the ones in which the contents of the reference can never change. Immutable Collections in the Scala Programming Language Therefore, today’s article will be dedicated to the collections in the Scala programming language in Ubuntu 20.04. However, as far as the Scala programming language is concerned, then it supports multiple different collections. A collection in Scala in particular or in any other programming language, in general, is simply a container that can hold the data.
