java遍历map的一种方法

Set<Map> set = new HashSet<Map>();
		for(int i=0;i<6;i++){
			Map<String, Integer> map = new HashMap<String, Integer>();
			map.put("1", 1);
			set.add(map);
		}
		for(Map<String, Integer> m:set){
			Set<String> s=m.keySet();
			  for (Iterator it = s.iterator(); it.hasNext();) {
		            String ss = (String) it.next();
		            System.out.println(m.get(ss));
		        }
		}
