| When Java introduced text blocks as a feature, it also introduced a new string |
| escape sequence `\s`. This escape sequence is another way to write a normal |
| space, but it has the advantage that it can be used at the end of a line in a |
| text block, where a normal space would be stripped. |
| |
| This new escape sequence can easily be confused with the regex `\s`, which is a |
| metacharacter that matches any kind of whitespace character. To write that |
| metacharacter in a Java string, you must still write `\\s`: an escaped backslash |
| followed by an `s`. |
| |
| There is little reason to ever write the Java escape `\s` except at the end of a |
| line. Either use a normal space, or switch to `\\s` if you are trying to write |
| the regex metacharacter. |
| |
| ```java |
| // Each line here is five characters long. |
| String colors = """ |
| one \s |
| two \s |
| three |
| """; |
| ``` |
