How to remove the empty line at the end when writing to a file?

Question

Java

Hello, please tell me, I have the following code:

PrintWriter out = new PrintWriter("files/out.txt");
     for(String email : result) {
         out.println(email);
       }
 out.close();

The output to the file looks like this:

How do I remove the last empty line? Thank you in advance for your response.

Answer 1

use print instead of println. The latter adds a line break after text output automatically. Add a break \n (or \r\n for windows format) manually at the end of lines, except for the last one.
