Bagaimana untuk Memindahkan Fail ke Soket dengan Betul di Java?

<code class="java">byte[] buffer = new byte[1024];
int bytesRead = 0;
while ((bytesRead = in.read(buffer)) != -1) {
    fos.write(buffer, 0, bytesRead);
}</code>

<code class="java">FileInputStream is = new FileInputStream(file);
byte[] bytes = new byte[(int) length];
is.read(bytes);
out.write(bytes);</code>

<code class="java">...
byte[] buffer = new byte[1024];
DataOutputStream out = new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
DataInputStream in = new DataInputStream(new BufferedInputStream(socket.getInputStream()));

FileOutputStream fos = new FileOutputStream("C:\test2.xml");
int bytesRead = 0;
while ((bytesRead = in.read(buffer)) != -1) {
    fos.write(buffer, 0, bytesRead);
}
fos.close();
...</code>

<code class="java">...
Socket socket = new Socket(host, 4444);
DataOutputStream out = new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
DataInputStream in = new DataInputStream(new BufferedInputStream(socket.getInputStream()));

File file = new File("C:\test.xml");
FileInputStream is = new FileInputStream(file);
long length = file.length();
if (length > Integer.MAX_VALUE) {
    System.out.println("File is too large.");
}
byte[] bytes = new byte[(int) length];
is.read(bytes);
out.write(bytes);
