How can I get rid of the 0D output when I use PrintWriter to write to file?
<p>code is working fine, I'm just curious as to how I can prevent the char 0D from printing at the end of my text file if at all possible. 
Thank you. 
here's the code if it helps. sorry if it's mediocre, still learning java. </p>
