Java程序设计电子英汉词典，帮忙根据我的程序写一个frame主类程序，在线等，急！！！

Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
Store store = session.getStore("pop3");
store.connect(host, username, password);
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
FetchProfile profile = new FetchProfile();
profile.add(UIDFolder.FetchProfileItem.UID);
profile.add(FetchProfile.Item.ENVELOPE);
if (folder instanceof POP3Folder) {
POP3Folder inbox = (POP3Folder) folder;
Message message[] = inbox.getMessages();
System.out.println("Messages's　length:　" + message.length);
for (int i = 0; i < message.length; i++) {
MimeMessage mimeMessage = (MimeMessage) message[i];
String uid = inbox.getUID(mimeMessage);
System.out.println("uid=" + uid);
int UnreadMessageCount = inbox.getUnreadMessageCount();
System.out.println("UnreadMessageCount="+UnreadMessageCount);
int NewMessageCount = inbox.getNewMessageCount();
System.out.println("NewMessageCount="+NewMessageCount);
URLName urlName = inbox.getURLName();
System.out.println("urlName="+urlName);

}
}
}

frame主类程序俺能指导你。

要添加一个顶层容器吗？
