scala -- trait

scala -- trait

A trait is a abstract class that is meant to be combined with other classes.

Some traits play the role of interface in Java, ie. they define a set of abstact methods which are implemented by some class.

But unlike interfaces, traits in Scala can also contain metod implementations or fields.
