A Simple Regular Expression...
Hey, im new to RegEx. Lets suppose I have the following:
import java.util.regex.*;
public class RegexValidation {
public static void main (String[]args){
String RE1="\\+?[09]* ?(\\(0\\))?[09. ]{7,}";
String RE2="\\w[.\\w]*@\\w[\\w]*\\.\\w[.\\w]*";
String RE3="\\w[,. \\w]*";
String RE4="[AZ]{1,2}[09R][09AZ]? [09][AZ[CIKMOV]]{2}";
//code here...?
}
}
I need to validate these contact details using the regular expressions int he String's. The question is:
contentmanager@bradford.ac.uk
University of Bradford
Bradford, West Yorkshire
BD7 1DP
UK
+44 (0)1274 232323
(i) Find the number of matches for each of the regular expressions RE14, taking as inputstrings whole lines in the contact details given above.
(ii) Suggest how to rename the regular expressions RE14 to indicate which details they validate, e.g. rename RE3 to EMAIL_RE (check!).
If you could please help me out, would be kind of you. Thank you :)

Re: A Simple Regular Expression...
on the first question of writing code:
(i) Find the number of matches for each of the regular expressions RE14, taking as inputstrings whole lines in the contact details given above.
Firstly, what is "RE14" ?

Re: A Simple Regular Expression...
ok I misread "each" lol, and how do I now actually find the number of matches for each of these regular expressions taken as input strings whole lines in the following contacts:
contentmanager@bradford.ac.uk
University of Bradford
Bradford, West Yorkshire
BD7 1DP
UK
+44 (0)1274 232323
and also how would I rename the regular expressions RE14 to indicate which details they validate please?

Re: A Simple Regular Expression...
The Java regular expressions tutorials shows you how to use a while loop to iterate through and "find()" each match.
and also how would I rename the regular expressions RE14 to indicate which details they validate please?
