List排序

      Collections.sort(lstMineForOneFile, new Comparator() {
         public int compare(Object a, Object b) {
          int orderA = Integer.parseInt(String.valueOf(((WorkProject)a).getSelfTaskId()));
          int orderB = Integer.parseInt(String.valueOf(((WorkProject)b).getSelfTaskId()));
           return orderA - orderB;
         }
      });

 

以WorkProject对象中的selfTaskId排序
