如何把bufferedinputstream 输出至bufferedoutputstre

如何把bufferedinputstream 输出至bufferedoutputstre

在服务器端设置代码：
BufferedInputStream infile = new BufferedInputStream(client.socket.getInputStream());
BufferedOutputStream outfile = new BufferedOutputStream(node.socket.getOutputStream());
byte[] b = new byte[1024];
int i = infile.read(b);
// FileOutputStream fos = new FileOutputStream(new File("e://Winter.jpg"));
try {
while (i!=-1) {
outfile.write(b, 0, i);
outfile.flush();
i = infile.read(b);
}
outfile.flush();
} catch (SocketException se) {
System.out.println("文件接受完毕");
}
