Perhaps all the data items stored in the three arrays could be put into a single new class so that, by definition, all the data would be sorted together. At that point, you might not need three separate arrays.
If you need to sort the data in different ways, you can avoid making copies of the List (to sort each one differently). Declare a static field in the class to indicate the sort method that you need at the moment, then read that static field in the compareTo() method. A user of that class that needs to sort a certain way would set the static field (say, through a sortMethodXXX() method you declare in the class) and call Collections.sort() as Sergio had previously suggested. If you might be calling the sort() method in a multithreaded environment, you'll have to take synchronization issues into account (to make certain that each thread uses the static field value needed to implement the sort method that thread needs). The suggestion above should work if you declare the sortMethodXXX() method as synchronized, but you'll need to test that carefully to make certain that one thread does not corrupt or delay the results expected within another thread. Hope this helps.

I mean, the first element of astrName have relation with first element of adblBackground1, adblBackground2, adblItensity1 and adblItensity2. Then I can sort each array independently, if I sort an element of astrName I have to sort the rest of arrays. Can you tell me a way to do this?
