Answer 1

If your requirement is to substring the left part before the @ and then split this substring using the . character, you can easily do this with the String class.

String leftPart = email.substringBefore('@');
String[] leftPartSplitted = leftPart.split('\\.');
//we check if there's one dot in the substring
if(leftPartSplitted.size() == 2){
   String firstName = leftPartSplitted[0];
   String lastName = leftPartSplitted[1];
}else{
   //there is no dot or more than one dot in the substring
}

You Have to know that your emailid and your account name for that email id can be different.

ex -

Name - William James Chadwick Potter
     email - [email protected]
  {First Name}+{Last Name} - {William} + {James Chadwick Potter}
                           - {William James} + {Chadwick Potter}
                           - {William James Chadwick} + {Potter}

Your Logic wont work here
