Question on getParameterNames and getParamaterValues return types

[Lorenz Baylon]

Does anyone know why getParameterNames returns Enumeration type while getParameterValues returns a String array? Is it possible that getParameterNames will return a collection of non-String values? Thanks.

Think about it, parameter names comes as a part of HTTP request, which is plain text, then how can getParameterNames return something which is not String...

[Lorenz Baylon]

Thanks Ankit, given that fact, then why does the getParameterNames return an Enumeration instead an array of Strings?

[Devaka Cooray]

Have a look at the javadoc for java.util.Enumeration - You may get the idea.

Thanks Devaka. Im not really sure if im getting it, but can't the getParameterValues method also return an Enumeration rather than a String array, with the same reason that the getParamaterValues method returns one?
