对一个文件列表进行排序

List<File> getList(List<File> list){

       List<File> listNew = new ArrayList<File>();
       listNew = list;
       if(!listNew.isEmpty()){
       Collections.sort(listNew,new Comparator<File>() {
          @Override
          public int compare(File object1, File object2) {
               return (object1.getName()).compareTo(object2.getName());
          }
       });
  }
        return listNew;
}
