I've some code below as that I use for querying the db and obtain that in my jsp file ,



The list returned looks something like [prefix1, no1, head1, amt1, prefix2, no2, head2, amt2,]. I'm trying to make a receipt in jsp on the lines of

head1
-------------------
prefix1/no1 amt1
-------------------
prefix2/no2 amt 2
-------------------
--------------------
head3
-------------------
prefix3/no3 amt3

So I want to group all records by head column in the receipt - jsp file. How do I go about this? Any help completely appreciated. Please excuse my English.
System.out.println("cash list: "+payincash);
