Java中怎么遍历map中value值 (转载)

 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());
  }
 }
