Set<Map.Entry<String, String>> mapEntrySet = map.entrySet();
for (Map.Entry<String, String> mapEntrySet : mapEntry){
String key =mapEntrySet .getKey();
String value =mapEntrySet .getValue();
System.out.println(key+ ":" + value);
}
加单案例如下：
获取所有键值对对象的集合Set<Map.Entry<k, v>> mapEntrySet = map.entrySet();
