java - Best way to display object properties

Question

Reflection or hashmaps? Suppose you are writting a graphical application where you have objects lying around and users have the posibility of clicking on them. That said, you want to display the clicked object information somehow.

I end up reading Accessible interface from accessibility java package and AccessibleContext class... Before that, I wrote testing code using hash maps for properties instead of class fields. And lastly, I thought in Reflection after reading that JavaBeans use instrospection.

What would you recommend in such applications?

Answer 1

Using reflection and introspection sounds like a better approach than using HashMaps. Instead of using this API directly, I would recommend an abstraction layer like Commons BeanUtils, which will allow you to work with classes adhering to the JavaBean standard in an easy manner.
