Question: What is Text Blocks or Multi-line string in Java 15?

Until now, when we wanted to define a multi-line string in Java, it usually looked like this:

String sql =
   "  SELECT id, title, text\n"
   + "    FROM Article\n"
   + "   WHERE category = \"Java\"\n"
   + "ORDER BY title";

Starting with Java 15, we can notate this string as a "text block":

String sql = """
  SELECT id, title, text
  FROM Article
  WHERE category = "Java"
  ORDER BY title""";
