No digits Java Regex Pattern

Question

I want a regex pattern to check that the string doesn't contain any digits .

For Illustration : I'm coding a Hospital System and I want from user to enter the name of the patient , Of course the name shouldn't contain any digits , how can I do this by Regex ?

Answer 1

\D is a non-digit, and so then \D* is any number of non-digits in a row. So your whole string should match \D*.

Answer 2

\A\D*\Z

Answer 3

Try: \D
