so give it a regex it.matches(Regex("\.[abc]\."))

[nkiesel]

That might still not do what is expected: this is the same as Regex(".[abc]."). If you want the . to be matched literally, use Regex("""\.[abc]\.""") or Regex("\\.[abc]\\.")

intelliJ lets you test it, so just give it a quick spin

Thank you both. I 've done some "spins" and ended with a pattern like ".+abc*.+" . The key point for me was ' Regex("foo") '. @nkiesel Your reply made a point! 👍
