Displaying image from binary file

Question

I am converting a image file(jpg) into a binary file and sending it. In the receiving side i got back the binary file and want to display the image in the applet or store the image in a file. while trying to do this i am not able to read the image from the buffer. Below here i have given my code.
File f= new File("image.jpg");
       FileInputStream fis = new FileInputStream(f);
       byte [] buffer = new byte[(int)f.length()];
       fis.read(buffer,0,buffer.length);
       fis.close();
      File f1 = new File("input.txt");
      int length = buffer.length;
      PrintWriter pw;
       pw = new PrintWriter(new BufferedWriter(new FileWriter(f1)));
      for(int i=0;i<length;i++)
          pw.println(Integer.toBinaryString(buffer));
pw.flush();
pw.close();
converting back to image i get error
File f1 = new File("inp.txt");
FileInputStream fis = new FileInputStream(f1);
buffer = new byte[(int)f1.length()];
fis.read(buffer,0,buffer.length);
Toolkit tk = Toolkit.getDefaultToolkit();
img = tk.createImage(buffer);
Reply me as early as possible.thanks.

Answer 1

You have two glaring problems here.
Firstly, you are writing via writers, which are intended for text and are probably corrupting your data. You want to be using a FileOutputStream.
Secondly, when reading in you are not checking the number of bytes read and may well not be fully populating your array. You want to change your reading code to something like this,
    buffer = new byte[(int)f1.length()];
    int read = 0;
    while (f1.available() > 0)
        read += fis.read(buffer, read, buffer.length - read);
    }
