JAVA jsoup解析网页时，并以列表方式输出，但采用键值对方式时出现错误，跪求解决！！！！

Question

部分代码：public static List> getKcList(String str) {
List> kcList = new ArrayList>();
Document doc = Jsoup.parse(str);
Elements datas = doc.getElementsByTag("table");
Element data = datas.get(0);
Elements trs = data.getElementsByTag("tr");
for (int i = 0; i < trs.size(); i++) {

       Elements tds = trs.get(i).select("td[rowspan=2]");
       for (int j = 0; j < tds.size(); j++) {



           if (!"".equals(tds.get(j).text())) {

                   kcList.add(getkcMap(tds.get(j).text()));

               }
           }

}
Log.i("Td","kcList"+kcList.size());
// Log.i("Th","kcList"+kcList.size());
return kcList;
}
/***************************

private static MapgetkcMap(String str){
String courseInfo[]=new String[]{
"课程编号：","课程名称：","教师号：","教师姓名：",
"上课时间：", "上课教室：","答疑时间：","答疑地点：",

    };
    String sCourse[] = str.split("\n");
    int i = 0;
    Map<String, String> map = new HashMap<String, String>();
    for (;i < sCourse.length; i++) {
        String s = sCourse[i];
        map.put(courseInfo[i], s);
        Log.i("Td", i + courseInfo[i] + "==" + s);
    }

    return map;

}

}

显示时： private void toShow(){
StringBuffer sb = new StringBuffer();
for(Mapmap:kcList){
for(String key : map.keySet()) {
if(!"".equals(map.get(key)))
sb.append(key).append(" ").append(map.get(key)).append(" ");
}
sb.append("\n----------------------\n");
}

  kb.setText(sb.toString());
}

}

显示结果出现错误如下：
