- 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<Message> email; public Mailbox() { this.email = new ArrayList<Message>(); } public Message…Java provides a mechanism that enables a program to be executed from the command line, as an application. Java runtime execution works on the basis that the class executed must have a: (constructor? inner class? method?) named `main’ that is: (final? static? local?) , public and void. This should take an : (StringBuffer? ArrayList? Array?) of Strings as its only argument. Execution is begun by (calling this method? clicking the BlueJ Run button? selecting this method from the dropdown menu?) . Select the correct answer.Program in Java Modify the Menu class: • Add a method to display the menu (the user choices) • Create objects to the Trim Molding, Carpet, and Ceiling Tile programs so they may be called from the Menu program.

Disk contains four fields: model (String), size (int), measure (String, for GB or TB), and performance index (int). -Disk needs a constructor to initialize all fields, a toString method, and an equals. Make the class Comparable and write a compareTo method that compares Disks based on the size of the disk. Make sure your comparison accounts for the fact that some numbers are in GB and some are in TB. Write a method that will return true if the disk is the same size as the parms; parms are the size and measure("GB" or "TB"). Also write a method to create a Comparator which compares Disks based on the performance rating. -The client code should do the following: Write a function called build, which will open the disks.txt file, read in each disk and add it to the BST. For each disk the model is on the first line, and the second line contains the size, measure, and performance index. The BST is passed to build as…Answer the follwoing question regading java:
