Sort a list

Hi All,

I have a list of objects in random order.

The object details are as follows :

String ID
String totalAmount

How can I order by totalamount so that the object with greatest total amount appears at the beginning of the list and so on.

Thanks

use following code

Collections.sort(yourList, new Comparator<MyObject>() {

    public int compare(MyObject o1, MyObject o2){
             if(o1.totalAmount == o2.totalAmount){
                   return 0;
              }else if(o1.totalAmount > o2.totalAmount){
                   return 1;
             }else if (o1.totalAmount < o2.totalAmount){
                   return -1;
              }
    }
});
