User Input Validation, enforcing a string containing only letters

Question

Im trying to make a user input validation system within one of my methods... its working fine to a cetain extent, but despite the code, its still allowing for integers as valid

Answer 1

I will take the code from Ubica. You can do it also like this. It is readable:

private boolean containsNumbers(String name) {
    char[] chars = name.toCharArray();
    for (char c : chars) {
        if (Character.isDigit(c)) {
            return true;
        }
    }
    return false;
}
