//text blocks were introduced in Java 13 as a Preview feature and in Java 15 as a full feature:
String a = """"""; // no line terminator after opening delimiter
String b = """ """; // no line terminator after opening delimiter
String c = """
"; // no closing delimiter (text block continues to EOF)
String d = """
abc \ def
"""; // unescaped backslash (see below for escape processing)
String html = """

<body>
<p>Hello, world</p>
</body>

""";
