Call

Collections.sort(myObjectList, comparator);

where comparator is a reference to an instance of Comparator<MyObject> which compares any two instances of MyObject appropriately.

Alternatively, if this is a "natural" sort order for MyObject, you could make MyObject implement Comparable<MyObject> and just call

Collections.sort(myObjectList);
