Some more info: 
 
I have an event array that I loop through: 
for (int i = 0; i &lt;&nbsp;event.length; i++) 
{ 
WebformsLabEvent wfle = new WebformsLabEvent(event[i]); 
WebformsLabObs wflo = wfle.findObs(&quot;5759&quot;); 
if (wflo != null) 
{ 
date = wfle.getCollectionDateTime(); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//Get the date of the lab 
result = wflo.getObsValue(); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//Get the lab value 
units = wflo.getUnits(); &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;//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 &nbsp; &nbsp;6.5 % 
02/15/2004 &nbsp; &nbsp;7% 
02/15/2004 &nbsp; &nbsp;3% 
02/16/2004 &nbsp; &nbsp;4.5% 
05/23/2002 &nbsp; &nbsp;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 &nbsp;4.5% 
4/30/2003 &nbsp; &nbsp;6.5% 
5/23/2002 &nbsp; &nbsp;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. &nbsp;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

Hello All, 
 
This should be fairly easy for someone: 
 
I get back from a query results: A date and a string (or many strings). I want to save these to an array, sort by date to get the latest date, and also remove any dates that are within one week of each other. 
 
How do I do that in Java? 
 
Thanks,

saving and sorting results in array - date sort

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
