User.java User is a class that represents a user in the music player application. Every User contains a library which stores all their Playlists. A User can create Playlists or add Playlists made by other users to their library. Additionally, they can also share Playlists with other Users. Each User has the following attributes: username - Represents the username of the user The name of a user should never be null library Represents the library of the User. A list that contains all the playlists the user has created or added. Every user's library will start with a playlist called "Liked" which stores the songs that the user has liked. This playlist should have a creation Date of 0. Save for the Liked playlist, a user's library should be sorted in order of recency. That is, a more recently created playlist should appear earlier than an older one. currentPlaying Represents the song the user is currently listening to. -If it is null, then the user is not listening to any song. User should…
What happens when you add an entry to a map with a key that already exists in the map?
Modify the Lab 6 java applet that produces a Bulls Eye with six concentric circles usingtwo colors as shown below. The applet should include a method that creates anddisplays a filled circle. The for loop should be modified to use the method. (See pg. 376,Programming Project 11, Savitch).The fillCircle method can be placed above or below the paint method and should bedefined using the following:private void fillCircle (Graphics canvas, int X, int Y, int diameter, Color color){canvas.setColor(color);canvas.fillOval(X, Y, diameter, diameter);}The program should continue to use Named Constants to establish and maintain the xand y settings for the circles and the amount to change the diameter for each circle.Use a for loop to control the drawing of each of the 6 circles. Within the loop, increasethe x, y settings; reduce the diameter for the new circle; and alternate the colors whencalling the drawCircle method. Test your code using the AppletViewer.Sample using AppletView
