Text blocks

Definition

A text block is a multi-line string written between triple quotes. It keeps line breaks and removes the common indentation, so JSON, SQL and HTML are easy to read in code without \n and escaped quotes.

Example code

A JSON string without escaping

class Demo {
    public static void main(String[] args) {
        String name = "Asha";

        String json = """
                {
                  "name": "%s",
                  "active": true
                }
                """.formatted(name);

        String sql = """
                SELECT id, name
                FROM users
                WHERE active = true
                """;

        System.out.print(json);
        System.out.print(sql);
    }
}

// Output:
// {
//   "name": "Asha",
//   "active": true
// }
// SELECT id, name
// FROM users
// WHERE active = true
