- Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).JAVA – color: String – make: String – model: String – msrp: double + Car() + Car(color: String, make: String, model: String, msrp: double) + getColor() : String + setColor(color : String ) : void + getMake() : String + setMake(make: String ) : void + getModel() : String + setModel(model: String ) : void + getMsrp () : double + setMsrp(msrp: double) : void + toString(): String The Car class will have four attributes/instance variables/fields and 11 methods. CarDealership Class The CarDealership class will simulate a real life automotive dealership. This class will create 3 Car objects and store them in an array named Lot. The class will then display all of the information pertaining to each car (color, make, model, etc.) to the User and allow the User to select one to purchase. Once the User selects a car to purchase, the Car object should be removed from the array (Lot) and another Car object should be put in its place.Create Playlist.java, Song.java, and PlayMusic.java. Song.java: models a song object; must have these members (you can add more members if needed): String name; String artist String album int time static int numSongs; Song(String name, String artist, String album, int time){} getName(){} getArtist(){} getAlbum(){} getTime(){} Playlist.java: models a playlist using an array of Song objects; must hvae the following members (you can add more members if needed): String name; String creator; Song[] songs; final int CAPACITY=20; //max size of a playlist Playlist(String name, String creator){} getName(){} addSong(Song song){} removeSong(Song song){} getSongs(){} Private data fields: Public methods: PlayMusic.java: This class will be the main class used to create and use Playlist and Song.

We'll use this to create Point objects that hold x,y coordinates of locations where we'll want to draw. Draw DotsWrite a drawDots(points) function that takes a list points as input and draws a dot on the drawing window for each Point. For example, you should be able to call your function as follows: >>> p = Point(10, 20) >>> q = Point(20, 30) >>> points = [p, q] >>> drawDots(points)Create a TeeShirt class for Toby's Company. Fields include: order Number - of type int , size - of type String , color - of type String.: Create set methods for the order number, size, and color and get methods for all four fields. The price is determined by the size, $22.99 for XXL or XXXL and $19.99 for all other sizes
