I'm looking for a java regex that will return true if a string contains any char[including special char _(underscore) and -(hyphen)] more than 3 times.

example : Heloooo --->True hellooo --->Flase Heleoeoe---> False

got one \w{0,2}$ working fine for JS but not for JAVA Can anyone help, thanks in advance?

Your JS regex doesn't seem right, but this (a|[^a])\1{3,} should work.

  • @sampadchakraborty Could you elaborate more on how it doesn't work? It seems to work for your test cases, at least. Perhaps I can help – user May 21 '20 at 15:42
