如何在java中使用它的鍵獲取Json值？

我有像下面給出的JSON數組。如何根據其鍵獲取值？如何在java中使用它的鍵獲取Json值？

$>

請把代碼JSON格式！ –

您可以使用[jsbeautifier]（http://jsbeautifier.org/）進行格式設置。正如我所看到的結果是不同的。例如檢查lsDur和lsDwn字段。這是一個錯誤嗎？ – saji159

第二件事WorkGroup ='應該更改爲'「WorkGroup」：'。你可以使用[jsonlint]（http://jsonlint.com/）valide JSON。 – saji159

使用下面的代碼來解析您的JSON字符串：

JSONArray jarray = new JSONArray("Your JSON String Here"); 

for (int i=0; i < jarray.length(); i++) 
{ 
    JSONObject oneObject = jArray.getJSONObject(i); 
    // Pulling items from the array 
    String oneObjectsid = oneObject.getString("id"); 
    String oneObjectsap = oneObject.getString("ap"); 
    String oneObjectsstatus = oneObject.getString("status"); 
    String oneObjectsname = oneObject.getString("name"); 
    //your rest code here... 
}
