Creating a new java.util.collection class

[memory721]

Hello,

I really need some help creating a new java.util.collection class.  When I create a multi-select query, the query sorts my criteria in descending order within the parameter clause.  The report itself is fine.  For example, if a user chooses the following criteria: Allow, Archive, Data Format, the report will show Data Format, Archive, Allow in the Parameter field on the report.

It was suggested to me that I should create a new java.util.collection class that will sort in ascending order.  I was wondering if I could just go into the current java.util.collection class and change it so that it will sort in asc?  I'm new to Java.  So this is a little beyond my skill set.  I'm trying to teach myself java because I can see that Jasperserver does require some Java knowledge.  I apologize, but I will need some help till I get up to par.

 

Thank you.
