Java Bean ?

[karthikeyan]

When can we call a class as JavaBean .?

[ray326]

The minimum requirement is an empty constructor and public get*/set* access to its otherwise private variables.

[karthikeyan]

I think it is necessary to implement java.io.Serializable or Externalizable

[vikassheelgupta]

I think when a class has some getter or setter methods and that class is serializable is said to be java bean

[shivaprasad]

Javabean components are known as beans.These components are in
javaAPI. Using API we write all reusable methods, such as set and get
methods in that class. such java class is called as javaBean

javabean is use in set and get so that the reusable method of class is their and it is called a JavaBean.
