What is a JavaBean exactly?

Question

I understood, I think, that a \"Bean\" is a Java class with properties and getters/setters. As much as I understand, it is the equivalent of a C struct. Is that true?

Answer 1

JavaBeans are Java classes which adhere to an extremely simple coding convention. All you have to do is to

1. implement java.io.Serializable interface - to save the state of an object
2. use a public empty argument constructor - to instantiate the object
3. provide public getter/setter methods - to get and set the values of private variables (properties ).
