Two '\n' characters between lines while reading File

[subith86]

Well, here goes my piece of code to read characters from a text file.

		File addressFile = new File("D://premdas/Desktop/address.txt");
		try {
			FileReader addressFileReader = new FileReader(addressFile);

			int c;
			while ((c = addressFileReader.read()) != -1) {
				System.out.println("reading--"+(char)c+"--");
			}
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}

And address.txt contains this

No.2, 3rd floor, 7th main,
E Block, Whitefield,
Bangalore, India
PIN - 560094

A portion of the output is as follows

reading--i--
reading--n--
reading--,--
reading--
--
reading--
--
reading--E--
reading-- --
reading--B--
reading--l--

This portion contains the ending part of first line, newline character and beginning portion of second line. As you can see the newline character is printed twice. But I'm sure in the address.txt, there are no empty lines between each line and each line immediately follows the other.

Can anybody tell why I am getting two newline characters while reading.

Are you sure those are two \n characters? Print the Unicode of each character and see for yourself:

System.out.println("reading--"+c+"--");

kind regards,

Thanks.
I checked. The first one is 10 (carriage return) and second is 13 (newline).
I have no idea about carriage return, what it is and why is it here.

I have no idea about carriage return, what it is and why is it here.

Windows uses this sequence of characters to separate lines.

Thanks, got it now.

As Pbrockway2 already wrote: it's MS Windows way to terminate a line; are you sure it's 10 followed by 13 and not the other way around? I thought the sequence is \r\n (13 10) ...

yes, I was wrong. It's 13(CR) and then 10(LF)
