What are the differences between JavaBeans and regular Java classes?

A JavaBean is a Java class that conforms to a specific specification and has the following characteristics:

1. JavaBean must have a no-argument public constructor in order to be instantiated using reflection.
2. Private properties: The attributes of JavaBean should be private and accessed or modified through public getter and setter methods.
3. Adhering to naming conventions: JavaBean properties should follow the camelCase naming style, with getter and setter methods named according to the standard “get” and “set” format.
4. JavaBeans can be made serializable by implementing the Serializable interface, allowing them to be serialized and deserialized for network transmission or storage.

In general, Java classes do not have specific requirements like having parameterized constructors or public attributes. JavaBeans are mainly used for encapsulating data, typically related to graphical interfaces and persistent data, while regular Java classes can be used for any purpose.
