saving and sorting results in array - date sort

Some more info:

I have an event array that I loop through:
for (int i = 0; i < event.length; i++)
{
WebformsLabEvent wfle = new WebformsLabEvent(event[i]);
WebformsLabObs wflo = wfle.findObs("5759");
if (wflo != null)
{
date = wfle.getCollectionDateTime();      //Get the date of the lab
result = wflo.getObsValue();      //Get the lab value
units = wflo.getUnits();      //Get the units of the lab
}
The display needs to look like this. I can format the date to do this after sorting with the full date:
Lab Name
04/30/2003    6.5 %
02/15/2004    7%
02/15/2004    3%
02/16/2004    4.5%
05/23/2002    6%
But I really want reverse date order and no results within one week of each other so it should look like this after:

Lab Name
02/16/2004  4.5%
4/30/2003    6.5%
5/23/2002    6%

Thanks.
 

Sorry, forgot to say that date is a Date, result and units are Strings, and I do not know the length of the results I will get back beforehand.

Thanks.

The following code will help you.  But you need to do calculations for your result and units related display

Below only checks the date and string comparision

if you want to calculate on float values then

you need to create the DateObject instance some thing like this DateObject obj=new DateObject(new java.util.Date(),new Double(6.5)) something like this.

Basically you need to have a comparator for this
