This interface allows the designer to specify information about the events, methods and properties of a Bean. Methods in this interface are used to initialize Beans that are also applets. The JavaBeans functionality is provided by a set of classes and interfaces in the java.beans package. This can be mitigated using tools like Lombok. Having to create getters for every property and setters for many, most, or all of them can lead to an immense quantity of boilerplate code.JavaBeans are inherently mutable and so lack the advantages offered by immutable objects.The compiler cannot detect such a problem, and even if it is documented, there is no guarantee that the developer will see the documentation. If such a class is instantiated manually by a developer (rather than automatically by some kind of framework), the developer might not realize that the class has been improperly instantiated. A class with a zero-argument constructor is subject to being instantiated in an invalid state.The configuration settings of a bean can be saved to persistent storage and restored.

Auxiliary software can be provided to help configure a bean.

A bean may register to receive events from other objects and can generate events that are sent to those other objects.

The properties, events, and methods of a bean can be exposed to another application.

A bean can provide other methods for business logic not related to the access to the properties. Methods A bean should use accessor methods to encapsulate the properties. Persistence Persistence is the ability to save the current state of a Bean, including the values of a Bean's properties and instance variables, to nonvolatile storage and to retrieve them at a later time. Events Beans may interact with the EventObject EventListener model. Customization A customizer can provide a step-by-step guide that the process must follow to use the component in a specific context. They are set through a setter method and can be obtained by a getter method. The values assigned to the properties determine the behaviour and appearance of that component.

Properties A property is a subset of a Bean's state. This is an essential feature of the Java Beans API because it allows another application, such as a design tool, to obtain information about a component.

Features Introspection Introspection is a process of analyzing a Bean to determine its capabilities.
