If you're not on Java 7 and can't use fge's solution, you may want to wrap your OutputStream in a BufferedOutputStream

BufferedOutputStream os = new BufferedOutputStream(new FileOutputStream("xx.txt"));

Such buffered output stream will write bytes in blocks to the file, which is more efficient than writing byte per byte.
