Hello everyone,

What's the difference between getParameterNames() and getParameterMap() while we can have the same result using one or another (We can extract pramater name and value from the quesry string without knwoning the prameter name previously)?

Thank you.

One gives you a list (via old-fashioned Enumeration) of the parameter names, the other returns a Map implementation of the names and their values.
