Java ArrayList 按照存储对象的属性进行排序

  List<SOilBusiness> sOilBusinesses2 = new ArrayList<>();
  ....(赋值)
  Collections.sort(sOilBusinesses2, new Comparator<SOilBusiness>() {
      @Override
      public int compare(SOilBusiness o1, SOilBusiness o2) {
          if (o1.getDistance() > o2.getDistance()) {
              return 1;
          } else if (o1.getDistance() == o2.getDistance()) {
              return 0;
          } else {
              return -1;
          }
      }
  });
