In computing based on the Java Platform, JavaBeans are classes that encapsulate many objects into a single object (the bean). They are serializable, have a zero-argument constructor, and allow access to properties using getter and setter methods. The name 'Bean' was given to encompass this standard, which aims to create reusable software components for Java.
