String.split method to split a string by dot and save it as arraylist

Am Fetching few lines from remote server and saving each line as an arraylist element by setting dot as a separator. Everything works fine. I just don't understand why a strange rn value gets appended to every new line.

E.g.:

I am going to School. I am feeling hungry

gets split and displayed as

I am going to School

rnI am feeling hungry

What does that rn stands for?

I am using String.split to separate. My code is below.

List<String> po= new ArrayList<String>();

separated_q = Arrays.asList(prdesc.split(Pattern.quote(".")));

for(int k=0;k<separated_q.size();k++) {
    po.add(separated_q.get(k));
}

Please help me point out where am wrong.

Remember, you are only splitting on the period, so if your text is:

I am going to School.
I am feeling hungry

the program sees this (especially on Windows):

I am going to School.\r\nI am feeling hungry

The \r is the carriage return character 0x0D and the \n is the linefeed character 0x0A. The split() isn't going to change anything with those characters, so you end up with 

string[0] = "I am going to School"
string[1] = "\r\nI am feeling hungry"

You should probably be splitting on the line break itself, rather that the period. To do that, you would code this:

separated_q = Arrays.asList(prdesc.split("\\r?\\n"));

That should also get rid of the "\r\n" you are seeing.

String myString = "I love writing code. It is so much fun!";

String[] split = myString.split(".");

String sentenceOne = split[0];
String sentenceTwo = split[1];
