Fundamental Types

Even though you can use any Java type in Scala, you can also enjoy a few types native to Scala. Scala makes a clearer distinction between value types and reference types and also goes a few extra miles with type definitions to enhance type verification and inference. Let’s get a grasp of these fundamental types since you’ll encounter these types in Scala quite often.

Any can serve as a common reference to objects of any type. Any is an abstract class with the following methods: !=, ==, asInstanceOf, equals, hashCode, isInstanceOf, and toString.
