What is a “Java Bean”? [duplicate]

Answer 1

A JavaBean is a Java object that satisfies below programming conventions:

1. The JavaBean class must implement Serializable Interface
2. The JavaBean class must have a no-arg constructor which should be public
3. All JavaBean properties must have public Setter and Getter methods to set and get all bean properties.
4. All JavaBean instance variables should be private and only accessible by Getter and setter.
