You only need to write the Song class in Java based on the ULM. Some of the method descriptions are below for this class. Will thumbs up

Description: In our earlier programs, the states of the objects we constructed at runtime were lost when the program stopped. For many applications, this is an unacceptable limitation. A word processor, for instance, wouldn't be very useful if we lost our documents when we turned off our computer. For our third lab, we will write a pair of classes that do not have this limitation: Song and Playlist. Playlist objects store a list of Song objects that can be modified in various ways. Most importantly, the state of a Playlist can be saved and loaded from a text file, so we can keep track of our music collection even after our program stops! 0..1 0..1 Class Diagram: Song -title: String -artist: String -minutes: int -seconds: int -numPlays: int -IDX TITLE = 0; int -IDX ARTIST = 1: int -IDX_LENGTH = 2: int - IDX_NUM PLAYS = 3: int +Song (info: String) +Song (other: Song) +getTitle(): String +getArtist(): String +getMinutes(): int +getSeconds(): int +getLength(): String +getNumPlays(): int +incrementPlays(): void +toString(): String Playlist -songs: ArrayList +Playlist) +Playlist(filename: String) - load(filename: String): void +save(filename: String): void +addSong (song: Song): void +addSong(index: int, song: Song): void +addSongs (filename: String): void +getSong(index: int): Song +numSongs(): int +playSong (index: int): void +removesong(index: int): Song +toString(): String +favoriteArtist(): String +totalPlaytime(): String tostrinsong(indi int): , Song Class: Each Song has a title, artist, length, and play count. The length is stored in two fields: minutes and seconds. Songs can be constructed from either an info String or another Song object. Info Strings have the following format: "
