map集合的遍历的几种方式

       Map集合的遍历：
publicstaticvoid main(String[]args) {
       Map<String ,String> map=new HashMap<String,String>();
       map.put("e_便利店+(k_远|k_偏)",
"13_005_005");
       Set<String> cons = map.keySet();
       for(String everyCon:cons){
           System.out.println(everyCon+"!!"+map.get(everyCon));
       }
       Iterator<String>it=cons.iterator();
       while(it.hasNext()){
           Stringkey=it.next();
           System.out.println(key+">>"+map.get(key));
       }
    }
