You could make a SortedSet out of the Map.Entry, providing a suitable
comparator at creation time. Something like this:
SortedSet<Entry<Integer, String>> set = new TreeSet<Entry<Integer,
String>> (theComparator);
set.addAll(Map.entrySet());
private static class TheComparator implements Comparator<Entry<Integer,
String>> {
public int compare(Entry<Integer, String> e1, Entry<Integer,
String> e2) {
if (e1.getValue() < e2.getValue()) {
return -1;
} else if (e1.getValue() > e2.getValue()) {
return 1;
} else {
return e1.getKey().compareTo(e2.getKey());
}
}
}
Also it might be worth checking Apache Commons Collections as it
(almost) for sure has what you need.

Hi.
LinkedHashMap will preserve order in wich elements are added to
LinkedHashMap, and checkboxlist (radiobuttons, etc) will be displayed
in that order.
