不懂，求大神教教，是遍历，然后再取类中的key和value吗

Question

public void browselist(Map<String, HomeworkList> map){


    Set<Map.Entry<String, HomeworkList>> set = map.entrySet();
    for(Iterator<Map.Entry<String, HomeworkList>> it = set.iterator();
            it.hasNext();){

        Map.Entry<String, HomeworkList> entry = (Map.Entry<String, HomeworkList>)it.next();

        System.out.println(entry.getKey()+"-"+entry.getValue());
    }

}

Answer 1

是的，遍历map，得到key和value，注意这个value是HomeworkList
