使用BufferedOutputStream通过while循环将字节写入文件.需要帮助 [英] Using BufferedOutputStream to write bytes to file with while loop. Help needed

问题描述

我正在尝试使用BufferedOutputStream将字节写入文件，但需要在while循环中工作.这意味着可以与TFTP服务器一起使用.它写入绝对没有任何内容的文件(这毫无意义).有人可以帮我吗?

I'm trying to write bytes to a file with a BufferedOutputStream but I need this to work in a while loop. This is mean to work with a TFTP server. It writes the file with absolutely nothing in it (which is pointless). Can anyone help me with this?

            WRQ WRQ = new WRQ();
            ACK ACK = new ACK();
            DatagramPacket outPacket;
            BufferedOutputStream bufferedOutput = new BufferedOutputStream(new FileOutputStream(filename));
            byte[] bytes;
            byte[] fileOut;
            outPacket = WRQ.firstPacket(packet);
            socket.send(outPacket);

            socket.receive(packet);

            while (packet.getLength() == 516){

            bytes = WRQ.doWRQ(packet);
            bufferedOutput.write(bytes);

            outPacket = ACK.doACK(packet);
            socket.send(outPacket);

            socket.receive(packet); 

            }

            bytes = WRQ.doWRQ(packet);
            bufferedOutput.write(bytes);

            outPacket = ACK.doACK(packet);
            socket.send(outPacket);

推荐答案

使用完流后，您不会关闭流.

You're not closing the stream when you're done with it.
