How to use NIO to write InputStream to File?

Question

I am using following way to write InputStream to File:

private void writeToFile(InputStream stream) throws IOException {
    String file         


        

Answer 1

I would use Files.copy

Files.copy(is, Paths.get(filePath));

as for your version

1. ByteBuffer.allocateDirect is faster - Java will make a best effort to perform native I/O operations directly upon it.

2. Closing is unreliable, if first fails second will never execute. Use try-with-resources instead, Channels are AutoCloseable too.
