Scala and Spark for Big Data Analytics

All types are objects

As mentioned earlier, every value in Scala will look like an object. This statement means everything looks like an object, but some of them do not actually object and you will see the interpretation of this in the coming chapters (for example, the difference between the reference types and the primitive types still exists in Scala, but it hides it for the most part). For example, in Scala, strings are implicitly converted to collections of characters, but not in Java!
