Reflection, introspection, and customization are somewhat dependent on each other. Visual builders need to expose a bean's properties to the users so that they can customize the properties. A tool or program must be able to introspect before it can allow a user to customize its beans. Therefore, you should provide a BeanInfo with references to default property editors or customized property editors.
You don't have to be writing an IDE or visual builder to make use of the reflection and introspection classes. They are also useful if you need to find out about third-party beans. You can develop an application that examines beans and determines their use on the fly to do whatever you want with them. Designing beans with customization is very important for developers who want to get their beans out the door. Users must be able to manipulate the beans that they buy, beg, borrow, or steal. You can easily make this possible by implementing a BeanInfo, property editors, and customizers for your beans.
