汉字转化为拼音

来源：互联网发布：java jdbc driver管理编辑：程序博客网时间：2024/04/29 05:05

很多问题都是因为中文问题造成的
如文件名最好别用中文
现在的解决方法一般是产生一个ID,将这个ID做文件名
网页上如果url带汉字也经常出错
现在的解决方法一般用urlencode编码

现在用了这个转化，就好多了

原理：利用哈希表技术 Hashtable ht=new Hashtable(10);

1.添加索引，如： ht.put("-20295","ang");
2.倒序遍历，如： while(!ht.containsKey(Integer.toString(num)))num--;

<%@ page language="java" import="java.util.*" contentType="text/html" %>
<%!
Hashtable ht=new Hashtable(10);
String g(Integer n){
int num=n.intValue();
if(num>0&&num<160){
return String.valueOf((char)num);
}
else if(num<-20319||num>-10247){
return "";
}
else{
if(ht.size()==0){b();}
while(!ht.containsKey(Integer.toString(num)))num--;
return ht.get(Integer.toString(num)).toString();
}
}
String c(String str){
char[] hz=str.toCharArray();
int len=str.length();
int p,q;
String ret="";
for(int i=0;i<len;i++){
p=(int)hz[i];
if(p>160){
q=(int)hz[++i];
p=p*256+q-65536;
}
ret+=g(new Integer(p));
}
return ret;
}
void b(){

用C#实现汉字转化为拼音
其实现的原理就是先将汉字转化成为内码，然后通过内码和拼音的对照来查找。

详细的代码如下所示：
