1、使用nio channel实现数据的读写

  public static void nioChannel() throws Exception
        String content = "hello, wys is beautiful views";
        FileOutputStream fos = new FileOutputStream("d:\\\\test.txt");
        FileChannel channel = fos.getChannel();
        ByteBuffer byteBuffer = ByteBuffer.allocate(1024);
        byteBuffer.put(content.getBytes());
        byteBuffer.flip();
        channel.write(byteBuffer);
        fos.close();
