Regular Expresion

[Naresh Rajan]

hi,
I am trying to match a string which can contain any digit except 6 as the first charecter. Can anyone please let me know how I do it.

Regards.

Have you looked at the API documentation of class java.util.regex.Pattern? It explains how to make a Java regular expression.

What did you try out yourself and how did that work out?

Here's a demo:

class Main {
    public static void main(String[] args) { 
        String regex = "[0-9&&[^6]][0-9]*";
        String s1 = "123456798a123";
        String s2 = "623456798123";
        String s3 = "123456798123";
        System.out.println("s1 ok? "+s1.matches(regex));
        System.out.println("s2 ok? "+s2.matches(regex));
        System.out.println("s3 ok? "+s3.matches(regex));
    }
}

Good luck.
