使用Javamail从邮件列表中查找特定的未读邮件

Question

MY approach is - 我的方法是-

Get the total mail list - 获取总邮件列表-

 List<Message> totalMessageList = Arrays .asList(folder.getMessages());

Create a list out of this which has only unread mails. 从中创建一个仅包含未读邮件的列表。 (I had to do this coz I could not find a any direct API to get list of new mails. One question which helped in finding whether a message is unread or not was posted here ) （我不得不这样做，因为我找不到任何直接的API来获取新邮件列表。一个帮助查找邮件是否未读的问题已发布在此处）
```
 List<Message> unreadMessageList = new ArrayList<Message>(); 
```
For sake of brevity I have not posted entire logic of building the list of unread mail from list of total mails. 为简洁起见，我没有发布从总邮件列表中构建未读邮件列表的完整逻辑。
Iterate through the list of unread mails > Check if any mail has desired subject then read content of mail > If no such mail found then throw IllegalStateExcepton 遍历未读邮件列表>检查是否有邮件主题，然后阅读邮件内容>如果找不到此类邮件，则抛出IllegalStateExcepton

Now my question is - Could I improve on this approach? 现在我的问题是-我可以改进这种方法吗？

Can you use 你能用吗

Folder.search(SearchTerm): Message[]

with the relevant SearchTerm, eg FlagTerm for the unread flag 与相关的SearchTerm一起使用，例如，未读标志的FlagTerm

Quick search on Google found this 在Google上进行的快速搜索发现了这一点

which might be useful, but I haven't tried it 这可能是有用的，但我还没有尝试过
