Sorry, I do get it
Yes, a bean is one kind of class written in a certain way.
The point was that they have to invent a terminology to describe a class that is not a bean, aka POJO.
Well, I'm sorry, but as far as I'm aware that is just "class" to everyone else.
The wider point I was trying to make is regards the terminology related to the different API infrastructures that are rife throughout the entire Java ecosystem. As a newcomer to Java, I found this an impenetrable barrier to understanding anything written about JAVA, that you need to know the current buzzwords to begin to get a grasp about that is being talked about.
Sorry to rant, it is just a bit of a bee that I have in my bonnet....
