------ Solution ------------------------------------ --------
Set is an unordered collection , the corresponding order is treeset, but I have not tried it, you can find some relevant information
------ Solution - ------------------------------------------
request.getParameterValue (" ; " ) that are ordered. .
------ Solution ---------------------------------------- ----
HTTP protocol does not define in browser implementations must act in order to obtain form in the form that appears . To fend for themselves in accordance with the form name defined in the order you want . such as a1 a2 a3. way . Then take their own name when sorting obtain .
SortedSet temp = new SortedSet();
Enumeration enumeration = request.getParameterNames();
while (enumeration.hasMoreElements())
{
temp.add((String)enumeration.nextElement());
}
------ For reference only ---------------------------------- -----
good I try

just know getParameterNames () to get the disorderly
------ For reference only ---------------------------------------
your parameters not there in the back corresponding attribute to receive it , or you can also in accordance with the corresponding property name obtained .

SortedSet temp = new TreeSet ();
It seems only the first and then took the custom sort the
