In depth understanding of JavaBeans and beans in Java

JavaBean is a special class in Java, which can encapsulate multiple objects into one object (bean).

It is characterized by serializability, providing parameterless constructors, and providing access object properties of getter methods and setter methods.

Bean in the name is a common name for reusable software components for Java.
