Comparable interfaces

[louie]

Hi there, i need a lot of help with this one. I need to create a list of objects that are actually the files in a computer system. Then i need to have them compared to one another to get the biggest ones and place them in an ArrayList. The trick is i have to specify the amount of files i want in the list and if i reach that number it is suppose to begin dropping the smallest files until I'm left with the biggest in the whole system.

Don't use a List; use a Map<Long, List<String>> where the key is the size of the file(s) and the value is a List of file names with that size. Make your Map a SortedMap (e.g. a TreeMap) so it is easy to drop the smallest element(s) from the map.

kind regards,
