File Problem (getting line ends with \r\n)

Question

I used readLine method     to read the line. It returns string.
I want to get the lined that ends with 0D0A ( \r \n ).
In the file in between there are many 0D. So my while loop
returns all the lines ends with 0D. But I need only the lines ending with 0D0A.
How can I differntiate these two types of lines
.....0D
...........0D0A
Is there any method in Java to differentiate these two lines.
reading char by char is time consuming process and it produce some overhead.
I think reading line by line gives the better solution
here is the code
import java.io.*;
class checkAcc {
public static void main(String as[]) {
try {
BufferedReader bf = new BufferedReader(new InputStreamReader(new FileInputStream("exa.dat")));
String s = null;
byte[] b;
while((s = bf.readLine()) != null) {
System.out.println("From Dat File ===> " + s);
} catch(IOException ie) {
System.out.println(ie);
Can any one pls give me the idea ...

Answer 1

That's the nature of readLine() my friend. The definition is as such:
Read a line of text. A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r'), or a carriage return followed immediately by a linefeed.
There isn't anything wrong (performance wise) with using read() and processing it character-by-character.
