    ```java
    String regex = "\\b(dog|cat)\\b";
    ```

Wouldn’t having ‘\b’ on both sides match beginning AND end? It’s got the parenthesis for the ‘|’ in the wrong place.

The regex I was expecting would be

    "\\b(dog.*)|(.*cat)\\b"

you regex will match the whole line up to cat.

The generated regex is the same as

    (\bdog\b)|(\bcat\b)

I’m currently trying to figure out how to match a word starting with dog without using

    \bdog.*

    .*

So I was thinking I could say

    \bdog[^\b]*

    \b(dog\S*)|(\S*cat)\b

https://regex101.com/r/sbpy8s/1

But this matches for example

    dog.cat

But I would like that it matches separately

    dog

    cat

Likewise, I’d want for example

    dogapple-bananacat

    dogapple

    bananacat

    \b(dog\p{L}*)|(\p{L}*cat)\b

But that does not match

    dog42

What I want is a way to include everything after dog that is not \b

And likewise everything preceding cat that is not \b

Edit: I think I’ve found it after reading https://stackoverflow.com/questions/4541573/what-are-non-wor...

    (\bdog\w*)|(\w*cat\b)

To me it feels like if 90% of $TASK content out there would be bad and people would struggle with it, then the AI-genrated $TASK output would be similarly flawed, be it regarding a programming language or something else.

As a silly example, consider how much bad legacy PHP code is out there and what the answers to some PHP questions could become because of that.

But it's still possible to get answers to simplistic problems reasonably fast, or at least get workable examples to then test and iterate upon, which can easily save some time.

  \bdog\w\*

    (\bdog\w*)|(\w*cat\b)

> i have found it to be terrible when it comes to something simple, like constructing a regex.

Oh yeah, agreed. It's not good for super specific stuff like that. But more like, I write a weird loop and ask if there is a more idiomatic way to do the above. Or I just describe what I want to do and say, "list three options for accomplishing that". It's great for "feature discovery" essentially. I find it complementary to copilot.
