json解析公交出错了，集合多了数据，这个怎么解决，求大神解决

Question

这段代码用json解析后，每一条线路都包含了正反两条线的站点信息，我的解析哪里错了？

下面的是我的解析
package com.tarena.busapp.util;
import android.util.Log;
import com.tarena.busapp.entity.Result;
import com.tarena.busapp.entity.Stationdes;
import org.json.JSONArray;
import org.json.JSONObject;
import java.util.ArrayList;
import java.util.List;
public class JSONParser {
private static Result result;
private static Stationdes st;
private static List stationdes;
public static List parseBusAry(JSONArray resultAry) throws Exception {
List resultList = new ArrayList<>();
stationdes = new ArrayList<>();
for (int i = 0; i < resultAry.length(); i++) {
JSONObject obj = resultAry.getJSONObject(i);
String terminal_name = obj.getString("terminal_name");
String line_id = obj.getString("line_id");
String key_name = obj.getString("key_name");

String code = null;
String stationNum = null;
String stationname = null;
String xy = null;
for (int j = 0; j < stationAry.length(); j++) {
JSONObject stationObj = stationAry.getJSONObject(j);
code = stationObj.getString("code");
stationNum = stationObj.getString("stationNum");
stationname = stationObj.getString("name");
xy = stationObj.getString("xy");
st = new Stationdes(code, stationNum, stationname, xy);
stationdes.add(st);
}
result = new Result(terminal_name, line_id, key_name, front_name, stationdes, start_time, company, length, end_time, name);
resultList.add(result);
}
Log.d("zkj", "" + resultList);
return resultList;
}
}
