What Is a JavaBean?
JavaBeans are simply pieces of reusable Java code that follow a strict set of rules on how they interface with other pieces of Java code. Any Java class that adheres to the rules regarding properties of interfaces can be a Bean. The best way to learn about JavaBeans is to experiment with them. Sun offers a free Bean Development Kit (BDK) through its Web site at www.sun.com (the BDK is available in the Products and API section of this site.) This site also contains documentation and tutorials on how to create and use JavaBeans through the Java class Beans. Note that the BDK is not meant for commercial application development, but merely for learning purposes. Many other JavaBean development kits are available if you want to develop Beans for commercial use.
| Tip | While you are at Sun's Web site, you may want to also download the Java Development Kit (JDK) along with many other Java utilities. The kit and documentation are free and provide an excellent way of experimenting with the Java language on a different platform, without having to pay for a compiler right away. |
