如何使用fillo从此Hashtable <integer，hashtable <string，string >>的输出中读取值

Question

公共哈希表> getdata（字符串查询）引发异常{         记录集记录= connection.executeQuery（query）;         ArrayList字段名称= records.getFieldNames（）;         Hashtable> rec = new Hashtable>（）;         //records.moveFirst（）;         int计数器= 0;         同时（records.next（））{             int size = fieldnames.size（）;             哈希表值= new Hashtable（）;             为（int i = 0; i

           values.put(fieldnames.get(i), records.getField(fieldnames.get(i)));
        }
        System.out.println(values);
        rec.put(counter, values);
        counter++;
    }
    return rec; 

输出为：

{TCNo = 1，标志= Y，ExcelName = Excel1，TestCaseScenrio = Scenario1} {TCNo = 2，Flag = Y，ExcelName = Excel2，TestCaseScenrio = Scenario2}
