请帮我看看这个，为什么还是不能显示中文

InputStream in;
OutputStream output;
Socket s;
int c;
StringBuffer strBuf = new StringBuffer();       
String str = domain+"\r\n";
try{       
        s = new Socket("whois.internic.net",43,true);
        s.setSoTimeout(30000);
        in = s.getInputStream();
        output = s.getOutputStream();
        output.write(str.getBytes());
        while((c=in.read())>;=0)
        {
                strBuf.append((char) c);
        }
        detail = new String(strBuf);
        detail = new String(detail.getBytes("ISO8859_1","gb2312";
        in.close();
        output.close();
        s.close();
        }
}catch (SocketException sEx)
{
}catch (IOException ex){
}
