9. Adding comments in text blocks

Question: Can we add comments in text blocks?

Official answer (according to the Java Language Specification): The lexical grammar implies that comments do not occur within character literals, string literals, or text blocks.

You might be tempted to try something like this, thinking it’s a quick hack, but I really don’t recommend it:

String txt = """  foo /* some comment */  buzz //another comment  """.replace("some_regex",""); 

Short answer: No, we cannot have comments in text blocks.

Let’s move on and talk about mixing ordinary string literals with text blocks.
