1、新增代码设计

* FileName:FileIO.java
* 处理文件的读写
*/
public class FileIO

public static String READ_PATH; //读取路径
public static String WRITE_PATH; //写入路径

/**
* 读取文件初始化地铁线路
*/
public static void readSubway(List < Station > map) throws IOException
File readfile = new File(READ_PATH);
BufferedReader reader = new BufferedReader(new FileReader(readfile));
String tempString = null;
while ((tempString = reader.readLine()) != null)
int trim = tempString.indexOf(‘ ‘);
String lineNo = tempString.substring(0, trim);
tempString = tempString.substring(trim + 1);
String[] stations = tempString.split(" ");

for (String s: stations) //初始化站点
Station test = new Station(s, lineNo); //要添加的车站
if (map.contains(test)) //已经有了
int index = (map.indexOf(test));
map.get(index).isInterchangeStation = true;
map.get(index).line.add(lineNo);
else
map.add(test);

for (int i = 0; i < stations.length; i++) //添加相邻站点
Station s = new Station(stations[i], lineNo);
int index = (map.indexOf(s));
if(stations.length==1)
break;

if (i == 0)
Station pres = new Station(stations[i + 1], lineNo);
int preindex = (map.indexOf(pres));
map.get(index).linkStations.add(map.get(preindex));
else if (i == stations.length - 1)
Station nexts = new Station(stations[i - 1], lineNo);
int nextindex = (map.indexOf(nexts));
map.get(index).linkStations.add(map.get(nextindex));
else
Station pres = new Station(stations[i + 1], lineNo);
int preindex = (map.indexOf(pres));
Station nexts = new Station(stations[i - 1], lineNo);
int nextindex = (map.indexOf(nexts));
map.get(index).linkStations.add(map.get(preindex));
map.get(index).linkStations.add(map.get(nextindex));



reader.close();

2.计划明天继续完成第一个功能，实现地图文本的读入

3.问题，之前没有见过实现读入的程序，设计，学习，查询询问过程比较艰难，进展缓慢。
