JSONArray key값 추출해서 사용하기

JSONArray array = new JSONArray(component);

System.out.println("array: "+ array);
JSONObject jobj = array.getJSONObject(0);

Set<String> keyList = jobj.keySet();

String table = "";

for(int i=0; i<array.length(); i++){
    JSONObject obj = array.getJSONObject(i);
    table += "<tr>";
    for(Iterator iter=keyList.iterator(); iter.hasNext();){
        String value = (String)obj.get(iter.next().toString());
        table += "<td>" + value + "</td>";
    }
    table += "</tr>";
}
System.out.println( table );
