遞歸JSON解析器

-1

我需要通過遞歸解析此JSON ..遞歸JSON解析器

你是什麼想要嗎？ –

我需要解析這個，並想設置爲spinners ..在選擇BE/ME/Btech之後，我需要獲得孩子數據[計算機科學在第二次微調]後，再次選擇計算機科學需要像第一年或第二年在單獨的微調器 – sree

所有的JSON解析器將遞歸解析通過樹。只需根據選定的鍵瀏覽java.util.Map。 – Gautam

我還沒有嘗試過，但在邏輯上應該以這種方式工作：

public void solve(JSONArray dataArray){ 
    try { 
     for(int i = 0; i < dataArray.length(); i++) { 
      JSONObject dataObj = dataArray.getJSONObject(i); 
      System.out.println(dataObj.getString("id")); 
      System.out.println(dataObj.getString("name")); 
      System.out.println(dataObj.getString("parent")); 
      JSONArray childArray = dataObj.getJSONArray("children"); 
      solve(childArray); 
     } 
    } catch(Exception e) { 
     e.printStackTrace(); 
    } 
}

try 
    { 
     JSONObject json=new JSONObject("response"); 
     JSONArray dataArray = json.getJSONArray("data"); 
     for(int i=0;i<dataArray.length();i++) 
     { 
      JSONObject dataObj=dataArray.getJSONObject(i); 
      System.out.println(dataObj.getString("id")); 
      System.out.println(dataObj.getString("name")); 
      System.out.println(dataObj.getString("parent")); 
      JSONArray childArray=dataObj.getJSONArray("children"); 
      for(int j=0;j<childArray.length();j++) 
      { 
       JSONObject childObj=childArray.getJSONObject(j); 
       System.out.println(childObj.getString("id")); 
       System.out.println(childObj.getString("name")); 
       System.out.println(childObj.getString("parent")); 
      } 

     } 
    } 
    catch(Exception e) 
    { 
     e.printStackTrace(); 
    }
