How to check whether a string contains at least one alphabet in java?

Question

I want such a validation that My String must be contains at least one alphabet.

I am using the following:

String s = "111a11";
boolean flag = s.matches("%[a-zA-Z]%");

flag gives me false even though a is in my string s

Answer 1

You can use .*[a-zA-Z]+.* with String.matches() method.

boolean atleastOneAlpha = s.matches(".*[a-zA-Z]+.*");
