This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
When a method need return an object list as result, I notice that two implementations exist in JDK. Some take java.util.Enumeration as return type (java.sql.DriverManager.getDrivers), and some take arrays (java.awt.Container.getComponents) instead. Of cource, other choices also there, for example, java.util.Iterator, etc. But, here, my question is on Enumeration and array: I wonder whether there's any resonable consideration when determining which is the appropriate return type?
