BeanUtil is a bean manipulation library that, in a nutshell, allows setting and reading bean properties. Several features make BeanUtil distinct:

  • fast (if not the fastest) bean manipulation utility

  • works with both attributes and properties

  • nested properties can be arrays, lists and maps

  • missing inner properties may be created

  • may work silently (no exception is thrown)

  • offers few populate methods

  • has strong-type conversion library

You can build your own implementation easily using BeanUtilBean, but these are already provided:
