Java Mailbox for Stored Email Addresses

Question

Hopefully somebody can help. I have successfully created a Java message class to model a standard email message but I am unsure how to proceed with a Mailbox class necessary to store the emails from the Message class.

Message Class

public class Message {    
    private String recipient;
    private String sender;
    private String message;
    private String body;

    public Message(String recipient, String sender){
        this.recipient = recipient;
        this.sender = sender;
    }

    public String toString(){           
        message = "From: " + recipient + "\nTo: " + sender; 
        return message;
    }

    public String append(){          
        body = "\nThis is the body content of your message";  
        return body;
    }
}

Mailbox Class

public class Mailbox {     
    public void addMessage(Message m)
    {

    }

    public Message getMessage(int i)
    {

    }

    public void removeMessage(int i)
    {

    }
}

A Vector / ArrayList can hold items / objects. So you can go to your mailbox class and create an ArrayList

ArrayList<Message> messages = new ArrayList<Message>();

Then you can add:

messages.add(new Message(...));

and delete:

messages.delete();

your messages.
