I had met with the scenario to sort this collection. Its Vector> .
i provided the example data.
[
{endtime=585, starttime=420},
{endtime=675, starttime=660},
{endtime=750, starttime=690},
{endtime=840, starttime=795},
{endtime=960, starttime=900}
]
the sort key is "starttime" for every elt in the vector.
the final result should be sorted based on the starttime value. please help me its urgent

If you are sure that u will have only one set of endtime and starttime in the hashtable; may be you can try something like this:
public void testSort() {
Vector> vector = new Vector>();
Hashtable table = new Hashtable();
table.put("etime", 900);
table.put("stime", 895);
vector.add(table);
table = new Hashtable();
table.put("etime", 210);
table.put("stime", 110);
vector.add(table);
table = new Hashtable();
table.put("etime", 590);
table.put("stime", 210);
vector.add(table);
System.out.println("B4------------------------------>");
System.out.println(vector);
List> l = new ArrayList>(vector);
Collections.sort(l, new Comparator>() {
public int compare(Hashtable o1, Hashtable o2) {
return o1.get("stime").compareTo(o2.get("stime"));
}
});
System.out.println("After ---------------------------------->");
vector = new Vector>(l);
System.out.println(vector);
}
