Question

I am trying to test a string (in java) for 9 adjacent identical numbers … I can test for adjacent identical numbers – but only the next adjacent number ….

boolean result = string.matches("/([0-9])\1/g");

I want to match 9 characters – anyone able to help me ?

Thanks

EDIT : Some examples

"1111111111" should match

"222222222" should match

"3311111111133" should match

"1234567890" should not match

Answer 1

Try this regex: ([0-9])\1{8}
