Non-blocking (NIO) reading of lines

Question

I need to read a file line by line using java.nio, but nio doesn\'t have a method like readline() to read one, complete line at a time

Answer 1

It works for me....

 public static void main(String[] args) throws IOException 
    {
        RandomAccessFile aFile = new RandomAccessFile
                ("F:\\DetailsMy1.txt", "r");
        FileChannel inChannel = aFile.getChannel();
        ByteBuffer buffer = ByteBuffer.allocate(1);
        StringBuffer line = new StringBuffer();
        while(inChannel.read(buffer) > 0)
        {
            buffer.flip();
            for (int i = 0; i < buffer.limit(); i++)
            {
                char ch = ((char) buffer.get());
                if(ch=='\r'){
                    System.out.print(line+"[EOL]");
                    line=new StringBuffer();
                }else{
                    line.append(ch);
                }
            }
            buffer.clear(); // do something with the data and clear/compact it.
        }
        inChannel.close();
        aFile.close();
    }
