Need help with regex{Resolved}

[Dillinger4]

Ive been trying to create a pattern that just matches three digits and three characters. Ive figured it out but in some instances it doesn't work quite right. Here's the pattern "(\\d{3}\\w{3})". "164Bdr" match, "121324" match but don't want to, "brd123" no match, "Brstd" no match.

It seems the pattern is failing on the \\d. The quantifer is greedy so that might be the problem.

Sounds fine by me.

import java.util.regex.*;
public class test{
    public static void main(String[] args){
        Pattern p=Pattern.compile("\\d{3}\\w{3}");
        System.out.println(p.matcher("164Bdr").matches());
        System.out.println(p.matcher("121324").matches());
        System.out.println(p.matcher("brd123").matches());
        System.out.println(p.matcher("Brstd").matches());
    }
}

Outputs

true
true
false
false

Ah ok i think i get it. Using "(\\d{3}\\w{3})" on "121324" the \\d is for digit [0-9] and \\w is for word character [a-zA-Z0-9] so true was correct. I would have to use \\D non digit [^0-9] "(\\d{3}\\D{3})"
