Write byte array to file in java

Question

I want to write byte array to txt file. Firstly I want to see that data in eclipse console and I see that data are true. But when I want to write this data into txt file the problem is manifest itself. Txt file is coming with errors.

My code is as follows.

FileOutputStream fos;
try {
    fos = new FileOutputStream("/usr/text110.txt");
    fos.write(imageInByte);
    fos.close();
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

My txt file is as follows. How can I save my byte array to file properly. Please help me.

Answer 1

FileOutputStream fos = FileOutputStream("path/to/the/file/to/write/in");
fos.write(theByteArray);
fos.close();

Will write the byte array in byte form.

FileOutputStream fos = FileOutputStream("path/to/the/file/to/write/in");
for (byte b : bytes) {
    fos.write(String.format("%02X ", b).getBytes());
}
fos.write(theByteArray);
fos.close();

Will write byte array in human readable form.
