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

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?

Solution

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

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