关于流问题

[lashengcrh]

try {
URL conn= new URL("http://www.sina.com/");
InputStream in=conn.openStream();
int n=in.available();
byte[] buf=new byte[1024];
while((n=in.read(buf))>=0){
System.out.write(buf,0,n);
}
in.close();
} catch (Exception e) {
e.printStackTrace();
}

1、如何将in中的数据写入文件呢？
2、如果网页上有中文，如何正确写入文件而不会出现乱码？
谢谢各位指点

        try {
            fout = new FileOutputStream("d://temp//1.html");
            URL conn= new URL("http://www.sina.com/");
            InputStream in=conn.openStream();
            int n=in.available();
            byte[] buf=new byte[1024];
            while((n=in.read(buf)) >=0){
                System.out.write(buf,0,n);
                fout.write(buf);
            }
            in.close();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if(fout != null) {
                try {
                    fout.close();
                } catch (IOException ex) {
                    ex.printStackTrace();
                }
            }
        }

少了一行

再来

        FileOutputStream fout = null;
        
        try {
            fout = new FileOutputStream("d://temp//1.html");
            URL conn= new URL("http://www.sina.com/");
            InputStream in=conn.openStream();
            int n=in.available();
            byte[] buf=new byte[1024];
            while((n=in.read(buf)) >=0){
                System.out.write(buf,0,n);
                fout.write(buf);
            }
            in.close();
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if(fout != null) {
                try {
                    fout.close();
                } catch (IOException ex) {
                    ex.printStackTrace();
                }
            }
        }

我在netbean中测试以上代码，最后出现报错，怎么办？

而且下载的网页格式很乱，不知如何下载完全的，单一的网页文件？

用字符流,不要用字节流直接读取,否则很容易出现非ascii码被截断出现乱码
