Java中怎么遍历map中value值

//两种方法，有问题，给我发百度消息 public static void main(String[] args){  Map<String, String> map = new HashMap<String, String>();  map.put("id1", "wang");  map.put("id2", "sheng");    //方法一  Set<String> set = map.keySet();   for (String s:set) {   System.out.println(s+","+map.get(s));  }  //方法二  Set<Map.Entry<String, String>> entryseSet=map.entrySet();  for (Map.Entry<String, String> entry:entryseSet) {   System.out.println(entry.getKey()+","+entry.getValue());  } }
