Below you are given the declaration of the MediaPlayer interface: public interface MediaPlayer $\{//$ Plays the media file void play$($String songName$)$; $//$ Pauses the currently playing media void pause$()$; $//$ Stops the media playback void stop$()$; $//$ Shows information about the current status String displayStatus$()$; $\}$ Implement the MediaPlayer interface in a class called SimpleMediaPlayer that includes: a private String attribute currentSong with corresponding getter getCurrentSong and setter setCurrentSong; a private String attribute status with corresponding getter. status can be one of the following values: "playing", "paused" or "idle"; a public constructor SimpleMediaPlayer$()$ which sets currentSong to an empty string and sets status to "idle"; the implementation of the play$($String songName$)$ abstract method, which sets currentSong to the value of the parameter songName and sets status to "playing"; the implementation of the pause abstract method, which: if currentSong is not an empty string, set the status attribute to "paused"; if currentSong is an empty string, it does nothing; the implementation of the stop abstract method, which: if currentSong is not an empty string, set the status attribute to "idle" and currentSong to an empty string; if currentSong is an empty string, it does nothing; the implementation of the displayStatus$()$ abstract method which should return: "Currently playing: $[$currentSong$]"$ when currentSong is a non$-$empty string and status is "playing"; "Media player is $[$status$]"$ when the status is not "playing". public interface MediaPlayer $\{//$ Plays the media file void play$($String songName$)$; $//$ Pauses the currently playing media void pause$()$; $//$ Stops the media playbac k void stop$()$; $//$ Shows information about the current status String displayStatus$()$; $\}$ public class SimpleMediaPlayer implements MediaPlayer $\{$ private String currentSong; private String status; $//$ Constructor initializing currentSong to an empty string and status to "idle" public SimpleMediaPlayer$()\{$ this.currentSong $=""$; this.status $=$ "idle"; $\}//$ Getter for currentSong public String getCurrentSong$()\{$ return currentSong; $\}//$ Setter for currentSong public void setCurrentSong$($String currentSong$)\{$ this.currentSong $=$ currentSong; $\}//$ Getter for status public String getStatus$()\{$ return status; $\}//$ Implementation of play method @Override public void play$($String songName$)\{$ this.currentSong $=$ songName; this.status $=$ "playing"; $\}//$ Implementation of pause method @Override public void pause$()\{$ if $(!$currentSong.isEmpty$())\{$ this.status $=$ "paused"; $\}\}//$ Implementation of stop method @Override public void stop$()\{$ if $(!$currentSong.isEmpty$())\{$ this.currentSong $=""$; this.status $=$ "idle"; $\}\}//$ Implementation of displayStatus method @Override public String displayStatus$()\{$ if $($status$.$equals$("$playing$"))\{$ return "Currently playing: $"+$ currentSong; $\}$ else $\{$ return "Media player is $"+$ status; $\}\}$ public static void main$($String$[]$ args$)\{$ SimpleMediaPlayer player $=$ new SimpleMediaPlayer$()$; player.play$("$Song A$")$; System.out.println$($player$.$displayStatus$())$; $//$ Currently playing: Song A player.pause$()$; System.out.println$($player$.$displayStatus$())$; $//$ Media player is paused player.stop$()$; System.out.println$($player$.$displayStatus$())$; $//$ Media player is idle $\}\}$
