 3 for (Iterator iter = map.entrySet().iterator(); iter.hasNext();) { 
 4 
 5     Map.Entry entry = (Map.Entry) iter.next(); 
 6 
 7     Object key = entry.getKey();     //得键
 8 
 9     Object val = entry.getValue();     //得值

11 }

15 Map map = new HashMap(); 
16 
17 for (Iterator iter = map.keySet().iterator(); iter.hasNext();) { 
18 
19     Object key = iter.next();         //得键
