Hi Palli,

 

Try following Class :

 

public class JstestController
{
public String email { get; set; }
public PageReference checkEmail(){
system.debug('#####email:'+email);
String emailPattern = email;
String emailRegex = '([a-zA-Z0-9_\\-\\.]+)@((\\[a-z]{1,3}\\.[a-z]{1,3}\\.[a-z]{1,3}\\.)|(([a-zA-Z0-9\\-]+\\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})';
Pattern MyPattern = Pattern.compile(emailRegex);
Matcher MyMatcher = MyPattern.matcher(email);
system.debug('#####validEmail :'+ MyMatcher.matches() );


return null;
}
}

 

Salesforce has standard pattern matching class. I hope above mention code will help you.

 

Thanks

Hi,

 

Why don't you use the built-in email field type?

Hi All,

 

MAGU's marked solution does not work 100% . It does not cater for john@doe (NO .com). Crop1645 is a more complete solution. Would you please update solution to correct solution.

Crop1645's solution also fails on john@doe..com

Crop1645's solution allows grave accent ` ASCII 96 but not apostrophe ' ASCII 39.  However email address can have ' prior to the @.
