Meaning – In Programming, the word Bean corresponds to JavaBean, which is a class that encapsulates many objects into a single object. This single object is nothing but the bean.
Beans in Java re serialisable, contain a zero-argument constructor and allow access to properties using the getter and setter method.
The Bean can also be defined as a reusable software component that be manipulated visually using an application builder tool.
Some of the advantages of using Java Beans are as follows –
- The properties, events and methods of the bean can be exposed to another application.
- A Bean can be registered to receive events from other objects.
- You can use auxiliary software to configure the bean.
- The configuration settings of the bean can be saved and restored at a later date.
Example of Usage – “JavaBeans is pretty compatible, there isn’t any new complicated mechanism for registering components with the run-time system.”
