Is there a way to read and write using the same FileChannel?

Question

I am new to Java NIO. I am seeing that a FileChannel object has both read and write methods. But I am unable to read and write using the same FileChannel at a single point of time. Is there a way to do so?

Unless you tell the problems you have faces in doing. It is difficult to answer. — Ramesh PVK, Jun 04 '12 at 05:25

Get a FileChannel from RandomAccessFile object with "rw" mode.

RandomAccessFile aFile     = new RandomAccessFile("abc.txt", "rw");
FileChannel      inChannel = aFile.getChannel();

If you obtain the FileChannel from a RandomAccessFile opened in "rw" mode you can both read and write. In all other cases you can't.
