如何在向量中存儲數據？

-1

我是新的黑莓，我不知道如何存儲數據在黑莓使用矢量。我需要存儲這些數據，所以請幫助我。如何在向量中存儲數據？

我解析成功使用json解析器。

try { 
     JSONObject root = new JSONObject(Data.data).getJSONObject("menu"); 
     JSONArray array = root.getJSONArray("menuitem"); 

    System.out.println("strMenu=="+strMenu); 
    for(int loop=0; loop<array.length(); loop++){ 
     System.out.println(array.getJSONObject(loop).get("type")); 
     System.out.println(array.getJSONObject(loop).get("name")); 
     System.out.println(array.getJSONObject(loop).get("url")); 
     JSONArray rows = array.getJSONObject(loop).getJSONArray("Row"); 
     for(int innerLoop=0; innerLoop<rows.length();innerLoop++){ 
      System.out.println(rows.getJSONObject(innerLoop).get("Index")); 
      JSONArray controll = rows.getJSONObject(innerLoop).getJSONArray("Control"); 
      for(int innermostLoop =0; innermostLoop<controll.length(); innermostLoop++){ 
       System.out.println(controll.getJSONObject(innermostLoop).get("type")); 
       System.out.println(controll.getJSONObject(innermostLoop).get("align")); 
       System.out.println(controll.getJSONObject(innermostLoop).get("send")); 
       System.out.println(controll.getJSONObject(innermostLoop).get("value")); 
       System.out.println(controll.getJSONObject(innermostLoop).get("param")); 
       System.out.println(controll.getJSONObject(innermostLoop).get("maxlength")); 
       System.out.println(controll.getJSONObject(innermostLoop).get("ctype")); 


       if(controll.getJSONObject(innermostLoop).get("type").equals("DD")) 
       { 
        JSONArray item=controll.getJSONObject(innermostLoop).getJSONArray("Item"); 
        for(int i=0;i<item.length();i++) 
        { 
         System.out.println(item.getJSONObject(i).get("name")); 
        } 

       } 

      } 
     } 
    } 
} catch (Exception e) { 
    e.printStackTrace(); 
    System.out.println("ZZZZZZZZ error ZZZZZZZ"); 
    // TODO: handle exception 
}

我想將所有數據存儲在一個向量中。在此先感謝。

試試這個 -

Vector vector = new Vector();

你的for循環中，將項目添加到載體。

vector.addElement(new your_object(value_1,value_2......));

新your_object（值1，值......）表示，請給我解釋一下更哥們Signare – user1443941

我想根據我的JSON數據存儲。 – user1443941

你想存儲什麼值。 String type = array.getJSONObject（loop）.get（「type」）;然後將該String類型添加到您的矢量以代替value_1。像那樣。 – Signare
