是这样的：
public static HashMap<String, String> telMap = new HashMap<String, String>();
public static HashMap<String, String> loadPhone(String filename)throws IOException {
try {
BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(
filename), "UTF-8"));
String str = null;
String key = null;
String value =null;
while ((str = br.readLine()) != null) {
String[] ss = str.split(" ", 2);
key = ss[0];
value = ss[1];
telMap.put(key, value);
}
br.close();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
return telMap;
}
上面一个方法是用来把一文本1内的内容装到telMap
这文本内的内容是：
11000000 北京市
11010000 市辖区
11010100 东城区
11010200 西城区
11010300 崇文区
类似这样的，前面的是城市区号编码，作为key
后面的是城市名称作为value
再有一个另外的文本2，里面的内容是
晋城
遵义
北京
柳州
海口
大理
德阳
想通过文本1给文本2的城市名都配上相应的城市编号
并写到文本3上，文本3的格式和文本1一样
文本2的城市名与文本1的城市名少了个市或县、区这种字，我知道如果是全字匹配，可以用下面的方法解决，但是现在少了个字，怎么解决啊
public void getPhoneAttribution(String cityname) {
try{
BufferedWriter bw = new BufferedWriter(new FileWriter("cityregion.data",true));
if (telMap.containsValue(cityname)) {
bw.write("\n"+cityname+" ");
bw.write(telMap.get(cityname));
} else {
System.out.println("the city's region is null!");
}
bw.flush();
bw.close();
}catch(Exception e){
e.printStackTrace();
}
}
再用这个containsValue应该不行吧？
------解决方案--------------------
你试一下下面的代码行不行
- Java code
public void getPhoneAttribution(String cityname) {try{BufferedWriter bw = new BufferedWriter(new FileWriter("cityregion.data",true));String cityName1=cityname+"区";String cityName2=cityname+"市";if (telMap.containsValue(cityName1)) {bw.write("\n"+cityName1+" ");bw.write(telMap.get(cityName1));}else{if (telMap.containsValue(cityName2)) {bw.write("\n"+cityName2+" ");bw.write(telMap.get(cityName2));}else {System.out.println("the city's region is null!");}} bw.flush();bw.close();}catch(Exception e){e.printStackTrace();}}
