How to output a Multiline Character Image in the console-CodePudding

I am developing a text-based game and I want to make the title something catchy. I tried to use a text to ASCII converter to make a nice-looking title and then copy and paste it in my code to output it, but it didn't work.

Here is what I tried to do:

System.out.println("
██████╗ ██╗   ██╗███╗   ██╗ ██████╗ ███████╗ ██████╗ ███╗   ██╗     ██████╗ ███████╗

But it didn't seem to work. I know it works in JavaScript, but I was wondering if it would also work in Java.

String literals

String literal - is a string consists of zero or more characters enclosed in double quotes "myText".

It is not possible to create a multiline string literal in Java, precisely as you've tried it. According to the language specification it's a compile-time error, line termination is present in a string lateral.

String invalidLiteral = "line1
                         line2
                         ..."; // will cause a compilation error

To make such string literal compile, line termination can be replaced with a new line character \n.

String validString = "line1\nline2\nline3";

The resulting string can become very long, in order to make it readable you can split the string into chunks concatenated with a plus sign , appending a new line character \n to each chunk.

String validConcatinatedString = "line1\n"  
                                 "line2\n"  
                                 "line3";

Although it'll work, it might be tedious.

Text Blocks

With Java 15 you can create a multiline string using text blocks available.

In order to create a text block, you need to enclose the target multiline text in triple double-quote characters """.

String myASCIIArt = """ // no text after the opening delimiter
              Your amazing 
                  ASCII art 
                       here""";

Note that the opening delimiter """ should be immediately followed by the line termination, and the actual body of the text block always starts on the next line.
