Get list of attributes of an object in an List

Question

When there is an List, is there a possibility of getting List of all person.getName() out of that? Is there an prepared call for that

Answer 1

Try this

Collection<String> names = CollectionUtils.collect(personList, TransformerUtils.invokerTransformer("getName"));  

Use apache commons collection api.

Answer 2

take a look at http://code.google.com/p/lambdaj/ - there is LINQ equivalent for Java. Using it won't avoid iterating all over items but the code would be more compressed.
