In java, implement a simple email messaging system. a message has a recipient, a sender, and a message text. a mailbox can store messages. supply a number of mailboxes for different users and a user interface for the user to login, send messages to other users, read their own messages, and log out. Given the code I have so far, what needs to be added? class Message { private String sender; private String recipient; private String messageText; public Message(String sender, String recipient) { this.sender = sender; this.recipient = recipient; this.messageText = " "; } public void append(String text) { this.messageText += text; } public String toString() { return "From: " + sender + " To: " + recipient + "\n" + this.messageText; } } class Mailbox { private ArrayList email; public Mailbox() { this.email = new ArrayList(); } public Message getMessage(int i) { return this.email.get(i); } public void addMessage(Message m) { this.email.add(m); } public void removeMessage(int i) { this.email.remove(i); } public int mailBoxSize() { return this.email.size(); } }
