In Bean class we have getter and setter methods.

Its just a naming convention.

Java Beans follow the Bean conventions:

(1) Default, no-arg ctor,
(2) Serializable,
(3) getX()/setX() or isX()/setX() naming convention for read/write access to private data member X,
(4) Can use java.bean.PropertyChangeEvent to notify interested parties when values change.
(5) Can use java.bean.PropertyChangeListener to register for notification when a particular property changes.

"Normal" Java classes aren't required to follow any of these conventions.

There's a great [url=http://java.sun.com/docs/books/tutorial/javabeans/]tutorial[/url] on Java Beans from Sun.

Answer 5

Java Bean is a simple java class that have setters and getter methods for declared variables, which in turn using in other java classes by calling this bean object.

Where as Enterprise Java Bean (known as EJB) is a different concept, is a separate architecture for setting up program components (other java programs).

Java Bean don't have business logic in it. EJB will have business logic in it.

Java Bean is a light weight componenet, EJB is a heavy weight component.

To run a Java Bean, Tomcat Server is sufficient, where as to run an EJB, we require an Application Server(Ex: Websphere, WebLogic etc..)

Answer 6

Netbeans is an Integrated Development Environment (IDE) for the Java programming language.

A JavaBean is just a Java class with a specific formatting.
