將JSON字符串導入到java

-2

是否可以將JSON字符串數組轉換爲java數組？將JSON字符串導入到java

對於類似這樣的http://api.soundrop.fm/spaces/XJTt3mXTOZpvgmOc

我需要獲取當前播放和藝術家值例子的東西。

你寫一個應該讀一個Java程序來自類似於您的帖子中鏈接的文本文件的字符串？請詳細說明。 – SebastianH

我認爲，因爲看到它是由一個網頁輸出它似乎很輕微，顯然我錯了。沒有文本文件，我有一個腳本來獲取鏈接的url並將其作爲字符串返回。 – Nonnisi

我建議使用json-lib到JSON序列化爲Java對象。

然後，您可以從該對象獲取JSONArray，並將其綁定到其自己的數組中。

例子：

JSONObject json = new JSONObject(jsonString); 
JSONArray owners = (JSONArray) json.get("owners"); 

Iterator<String> iterator = owners.iterator(); 
while (iterator.hasNext()) { 
    System.out.println(iterator.next()); 
}

輸出：

Wr3pWSGt54GlRiEL 
XJU7ZqZ3MYrQncIw

格式化JSON：

這是JSON格式，或至少它看起來像它，也有JSON的Java解析器所以請嘗試使用它，它就會產生地圖，而不是一個數組
