编码转化问题

[chenguokui]

package bs;

import java.net.*;
import java.io.*;

public class GetHtml {
public String gethtml(String addr) {

try {
URL url = new URL(addr);
BufferedReader br = new BufferedReader(new InputStreamReader(url
.openStream()));
String html = "";
StringBuffer sb = new StringBuffer("");
while ((html = br.readLine()) != null) {
sb.append(html + "\r\n");
}
br.close();

return sb.toString();
} catch (Exception e) {
return addr + "is error url";

}

}

public static void main(String[] args) {
GetHtml gh = new GetHtml();
String get_html = gh.gethtml("http://www.baidu.com");
try {
System.out.println(new String(get_html.getBytes("gb2312")));

} catch (Exception e) {
System.out.println(e.toString());
}

}
}

我的工作平台是linux，baidu的编码是gb2312，我用getbytes进行转化，但是还是乱码，为什么

你还要看自己的linux是什么编码，如果是utf-8，在new String(get_html.getBytes( "gb2312 "))的时候还要加上utf-8这个参数
