Answer» There is no SPECIFIC rule when you can use traits, but there is a guideline which you can consider. If the behaviour will not be reused, then make it a concrete class. Anyhow it is not a reusable behaviour. In order to inherit from it in Java code, an abstract class can be USED. If efficiency is a priority then LEAN TOWARDS using a class Make it a trait if it might be reused in MULTIPLE and unrelated classes. In different parts of the class hierarchy only traits can be mixed into different parts. You can use abstract class, if you want to distribute it in compiled form and expects outside groups to write classes inheriting from it. There is no specific rule when you can use traits, but there is a guideline which you can consider.
