#CASE SCALA HOW TO#
Try the following example program, which shows how to match against an integer value. Keywords are reserved words used for naming actions. An arrow symbol => separates the pattern from the expressions. At the most basic level, Scalas Match Case is just like a switch statement in Java or C++. Each alternative includes a pattern and one or more expressions, which will be evaluated if the pattern matches. Match case is the foundation for the pattern matching in Scala.

Scala provides great support for pattern matching, in processing the messages.Ī pattern match includes a sequence of alternatives, each starting with the keyword case. However, it only creates one to match the primary constructor and will.

The objects of this class can be instantiated even. For case classes, Scala automatically creates a factory method in the companion object. Pattern matching is the second most widely used feature of Scala, after function values and closures. To use case-insensitive in an existing SBT project with Scala 2.12 or a later version, add the following dependencies to your build.sbt depending on your. The Case class in Scala is pretty much like a regular Scala class but with some additional functionality.
