* You will write a method that converts a JSON Object into a Song object. It should assume that the input is in the format:
* {"title":"Lose Yourself", "artist":"Eminem", "ratings":[5,5,4,5], "youtubeID":"xFYQQPAOz7Y"}
*
* @param jsonSong A song in JSON format
* @return A Song object with the data from the JSON Value

public static Song jsonToSong(JsonObject jsonSong){
String title =jsonSong.get("title").asString();
String YoutubeID =jsonSong.get("youtubeID").asString();
String artist =jsonSong.get("artist").asString();
ArrayList<Integer> ratings = new ArrayList<Integer>();
Song object = new Song(YoutubeID,title,artist,ratings);
object.setTitle(title);
object.setArtist(artist);
object.setRatings(ratings);
object.setYoutubeID(YoutubeID);
return object;
我已經編寫了將JsonObject轉換爲類型Song對象的代碼,除了arraylist(ratings)以外,所有內容都進行了轉換。獲取從另一個類arrayList中獲取數據?
如何使用getter和setter方法正確檢索數據?
我的getter setter方法是:
public ArrayList<Integer> getRatings(){
return ratings;
}
public void setRatings(ArrayList<Integer> ratings){
this.ratings = ratings;
}
構造:
// Constructor
public Song(String youtubeID, String title, String artist, ArrayList<Integer> ratings){
this.youtubeID = youtubeID;
this.title = title;
this.artist = artist;
this.ratings = ratings;
}
在這裏,你可以看到這一切轉變,除了等級,當通過分級機
Incorrect on input: {"title":"Comfortably Numb","artist":"Pink Floyd","ratings":[5,4,5,5],"youtubeID":"_FrOQC-zEog"}
Expected output : {title:Comfortably Numb, artist:Pink Floyd, ratings:[5, 4, 5, 5], youtubeID:_FrOQC-zEog}
Your output : {title:Comfortably Numb, artist:Pink Floyd, ratings:[], youtubeID:_FrOQC-zEog}
Score: 0
有什麼相同的數據傳遞到您的構造函數和setter的意義呢?你的問題到底是什麼? – shmosel
我需要使用來自arraylist評分的數據,這些數據看起來像這樣[5,6,5]放入SongObject評分中。 – Gintoki
