Can single String contain multiple lines?

Question

For example if I assign multiple lines to a string as so:

while ((line = reader.readLine()) != null)
        {
            output += line + \"\\n\";
        }
         


        

Answer 1

why not just move this to outside the while loop?

    System.out.print("Enter your choice: ");
    fromClient = stdIn.readLine().trim();
