Writing binary files

An efficient way of writing binary files is by using BufferedOutputStream. For example, writing a byte[] to a file can be accomplished as follows:

final byte[] buffer...;Path classFile = Paths.get(  "build/classes/modern/challenge/Main.class");try (BufferedOutputStream bos = newBufferedOutputStream(    Files.newOutputStream(classFile, StandardOpenOption.CREATE,      StandardOpenOption.WRITE))) {  bos.write(buffer);}

If you're writing byte by byte, use the write(int b) method, and, if you're writing a chunk of data, use the write​(byte[] b, int off, int len) method.

A very handy method for writing a byte[] to a file is Files.write​(Path path, byte[] bytes, OpenOption... options). For example, let's write the content of the preceding ...
