Writing to files with Java

Question

I am currently writing a programming a webserver, I am working on the HTTP PUT method. When the client is connect and he types something like this:

PUT /newfile.txt HTTP/1.1
Host: myhost
BODY This text is what has to be written to the new created file

I want to be able to write the BODY of the client request into the created file.

This is what I have to far, it work but after I press enter it stays there.

InputStream is = conn.getInputStream();
OutputStream fos = Files.newOutputStream(file); 

int count = 0;
int n = 10;

while (count < n) {
        int b = is.read();
        if (b == -1) break;
        fos.write(b);
        ++count;
}

fos.close();
conn.close();

it stays where? is will not return -1 until the connection input stream is closed — Martin Serrano

You may try this

Scanner sc = new Scanner(is);

Scanner will enable you to read file easily to a String. You may separate BODY using regex. You just have to provide it as an argument of the next method of Scanner.

After separating, you'll need to write that String to the file. Just use

FileWriter writer = new FileWriter(file);
writer.write(bodyContentString);
writer.flush();
writer.close();

Good luck.
