没有数字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

a good regex cheatsheet here

Answer 3

Try: \\D

See the JavaDoc for Pattern

Answer 4

Well names usually alphabetical, so this will be good : [ab,AZ, ,-]+

EDIT : [a-zA-Z- ',]+
