1. You are required to implement all the classes as specified by UML diagram below.The objective
of most of the methods is obvious from the given method name and input parameters.I am listing
below the explanation of the not-so-obvious methods.
PlayList Class:
getSong(pos:int) :Song
a method that returns the song that is located in the given position (pos). If there is no song in the
given position then the method returns null
getSongPosition(title:String):int
a method that takes the song title as input and returns as output the position of the song in the
list. If not found, the method returns -1. Song -title:String -artist: String +Song (title:String,
artist:String) +gettitle ():String +getArtist ):String +tostring ) :String PlayList
maxNumOfSongs:int -currentNumor Songs: int; +PlayList (maxNumOESongs:int)
+getcurrentNumSongs ) :int +addsong (title:String, artist:String) :void +addsong
(song:Song):void +getsong (pos:int) :Song +getsongPosition (title:String) :int User nam String -
favoriteSongs: PlayList +User (name: String, favoriteSongs: PlayList) +User (name: String)
