java HashMap 迭代器循环 和 删除指定key

//声明map集合
Map<String,String> PubJudgeGroupRelationList = new HashMap<>();
	//迭代器循环
		Iterator<Entry<String, String>> iter=PubJudgeGroupRelationList.entrySet().iterator();
		while (iter.hasNext()) {
			Map.Entry<String, String> info = iter.next();
			System.out.println("循环"+info.getKey()+"/"+info.getValue());
			//判断key值.equals(值) 如果等于就删除这个key
			if (info.getKey().equals(“1024”)) {
				iter.remove();
			}
		}
