A simple question. Is it possible to have comments in Text Blocks in Java 17?
Since Java 15 Text Blocks are an option:
"""
Hello Hello //how to create a comment here? - this was wanted by customer XXX
This dog has a big nose // This line came with version 1.0.2
This cat needs to eat
"""
Is it possible to have comments inside a text block? I would like to tag some lines that came with new customers etc. Is this possible, will this be possible?
I don't know specially for Java but I would think that no it isn't possible to do this as some people would want to have text with // in the strings without escaping.
As of JEP 378, it is not possible to add a comment in a text block.
However, you can use a few tricks:
For example, you can replace everything inside of /*... */:
"""
abc /* this is a comment*/
def //another comment
""".replace("/\\*.*\*/","").replace("//.*$","");
Another possibility would be to use multiple text blocks:
"""
...
"""
+ //comment
"""
...
"""
However, as Federico klez Culloca mentioned in the comments, these are just workarounds. It is likely better to include a comment before the text block explaining what it does in general instead of writing comments in the text blocks.
