Daripada blog gak diupdate... mending diisi codingan iseng sy.. huheue
gak usah pake treebidimapnya jakarta apache commons..

TreeMap tm = new TreeMap();
tm.put(4L, 10f);
tm.put(2L, 1f);
tm.put(1L, 5f);
TreeSet set = new TreeSet(new Comparator(){
public int compare(Object obj, Object obj1) {
float o =((Float)((Map.Entry) obj).getValue()).floatValue();
float o1 =((Float)((Map.Entry) obj1).getValue()).floatValue();
if (o>o1) return -1;
else if (o<o1) return 1;
return 0;
}
});
set.addAll(tm.entrySet());
for (Iterator i = set.iterator(); i.hasNext(); ) {
Map.Entry entry = (Map.Entry) i.next();
System.out.println(entry.getKey() + " - " + entry.getValue());
}

output:

4 - 10.0
1 - 5.0
2 - 1.0

Kemaren abis moto2 dikraton, gak tau deh..pas diliat kok muncul beginian.. penampakan?
