HashMap的遍历

HashMap的遍历

1、新建一个HashMap

Map<Integer , String> notProcInfo = new HashMap<Integer , String>();

2、往HashMap中增添数据

notProcInfo.put(infoId, infoTitle);//infoId为int型，infoTitle为String型

3、遍历HashMap

Iterator<Entry<Integer, String>> iter = notProcInfo.entrySet().iterator();while(iter.hasNext()){        Map.Entry<Integer, String> info= iter.next();        int key = info.getKey();//获取健        String content = info.getValue();//获取值}
