Question

java中如何修改字符串编码？

Answer 1

假设你的字符串的字节数组是buf，按照GBK解析这个字符串的方法就是如下
String
str=new
String(buf,0,buf.length,"GBK");
如果是utf-8编码，就把GBK换成utf-8即可

Answer 2

StringBuilder
sb
=
new
StringBuilder();
//
创建URL
URL
url
=
new
URL("GBK
page
URL");
//
打开请求链接
URLConnection
page
=
url.openConnection();
//
以GBK格式读取返回流
BufferedReader
in
=
new
BufferedReader(new
InputStreamReader(page.getInputStream(),"GBK"));
//
读取流内容
String
inputLine;
while
((inputLine
=
in.readLine())
!=
null)
{
sb.append(inputLine);
}
sb.toString();
