遍历map类型的数据

Map<String,String> params = new HashMap<String,String>();
??params.put("name1", "taohaibing");
??params.put("name2", "taohaibing2");
??
??Map.Entry<String, String> param = null;
??Iterator iter = params.entrySet().iterator();
??while(iter.hasNext())
??{
????? param = (Entry<String, String>) iter.next();
????? System.out.println(param.getKey()+":"+param.getValue());
???
??}
