What are the differences between JavaBeans and Java classes?

JavaBean is a specific type of Java class that follows certain naming conventions and programming agreements. The difference between JavaBean and a regular Java class is as follows:

  1. Naming conventions: JavaBeans are typically named using camel case, with the first letter of the class name capitalized. Additionally, a default no-argument constructor should be provided for JavaBeans.
  2. Encapsulation: JavaBeans typically use private member variables and provide access and modification to these properties through public getter and setter methods. This allows for encapsulation of properties and control over access permissions.
  3. Serializability: JavaBeans typically implement the Serializable interface to support object serialization and deserialization, allowing objects to be transmitted over a network or stored in a file.
  4. Event handling: JavaBeans can support event handling and callbacks by adding property listeners (PropertyChangeListener) and event listeners (ActionListener).
  5. Reflection: JavaBeans can utilize reflection to dynamically access and modify property values, as well as invoke their methods.

In conclusion, JavaBean is a type of Java class that adheres to specific standards and conventions, used for encapsulating data and providing access methods for properties. Compared to regular Java classes, JavaBean has stricter naming conventions, property encapsulation, support for serialization, event handling, and reflection.
