definition - What is a "Java Bean"?

Question

(This question already has answers here): question from:https://stackoverflow.com/questions/1973073/what-is-a-java-bean

Answer 1

Any serializable java class (implementing java.io.Serializable) that follows specific conventions: a no-argument constructor, and properties accessible via get/set/is accessors.

The idea is to make it predictable, so that properties etc can be discovered automatically through reflection - of great help in tool and framework development.
