I have an inputStream and i want to write it to a file.

I saw NIO and the FileChannel which has the method “transferTo” ou “transferFrom” and i know how to create the WriteableChannel, but i don’t know to transform my inputStream to a ReadableChannel.

Thanks.

    Have a look at the Channels.newChannel(java.io.InputStream) method.

    newChannel

      public static ReadableByteChannel newChannel(InputStream in)
    Constructs a channel that reads bytes from the given stream.

    The resulting channel will not be buffered; it will simply redirect
    its I/O operations to the given stream. Closing the channel will in
    turn cause the stream to be closed.

    Parameters:in – The stream from which bytes are to be read
    Returns:A new readable byte channel
