hi guys!!

can anybody tell me how to validate a set of email id 's using java..

You can use the Regular expressions facilities...

Quote:

---

import java.util.regex.*;

class regexSample
{
public static void main(String args[])
{
//Input the string for validation
String email = "xyz@hotmail.com";

//Set the email pattern string
Pattern p = Pattern.compile(".+@.+\\.[a-z]+");

//Match the given string with the pattern
Matcher m = p.matcher(email);

//check whether match is found
boolean matchFound = m.matches();

if (matchFound)
System.out.println("Valid Email Id.");
else
System.out.println("Invalid Email Id.");
}
}

pjmorce, it's better give a guide first, before posting a code segment. Reason is our thread poster can confused as well as he/she doesn't learn new things and like to wait until someone post a code segment for there question in future. :)

You are right.

Here goes a little tutorial explaining the goal of regular expressions and how they can be used with Java...

That's really nice lol. :)

The regex posted up thread is at best a decent first pass. The actual format is a lot more complex. Some of the complexity is probably no longer needed, but the official spec is RFC822
