 public class letter
    {
     public static void main(String[] args)
    {
      System.out.println("+----------------------------------------------------+
                       |                                           ###      |

code2[errorless]

  public class Lettertoyourself

  public static void main(String[] args)
  {

   System.out.println("|                                           ###      |");

don't post links to code, post your actual code here, allong with any error(s) or error messages you get — Stultuske, Feb 20 '19 at 14:31
You'll need to copy and paste the code here, we can't tell from just an image. Likely you've got a weird character in there somewhere. — markspace, Feb 20 '19 at 14:31
Java doesn't do multi-line strings (yet), see https://www.vojtechruzicka.com/raw-strings/ — BretC, Feb 20 '19 at 14:32
Java does not support multiline-strings. (not yet, at least) — Zabuzard, Feb 20 '19 at 14:33

Java doesn't support multi-line strings.

You need to put in the newlines yourself:

System.out.println("  line 1\n  line 2\n  line 3");

or, if you think it more readable:

System.out.println("  line 1\n" +
                   "  line 2\n" +
                   "  line 3");

or:

System.out.println(
    Stream.of(
        "  line 1",
        "  line 2",
        "  line 3").collect(joining("\n"))));

You can replace "\n" with System.lineSeparator() if you want; but I would only really suggest doing that in the third of the styles shown here, as otherwise it will seriously harm the readability of the code.

Yet. Hopefully soon. – Thorbjørn Ravn Andersen Feb 20 '19 at 14:35
You may prefer `System.lineSeparator()` to `\n`. – Zabuzard Feb 20 '19 at 14:35

@Zabuza you might, but oof, the readability hit. – Andy Turner Feb 20 '19 at 14:36

Agreed. How about `printf` with `%n` :) – Zabuzard Feb 20 '19 at 14:36
@Zabuza that's fine provided you don't have anything in the string which would otherwise be interpreted as a format specifier. – Andy Turner Feb 20 '19 at 14:41

public static void main(String arg[]) {


    System.out.println("+--------------------------------------------+"
            + "|                                                     |"
            + "                                                     ");

}
}

you just need to add + " " for every line , i dont know what u mean by multip system.println but yes you can store the lines on a String var , and then print all of them using one system.print ln
