How can I do this?

Answer 1

Here's an example, email can be any email address, not just gmail.com

public class Test  {

  public static void main(String[] args)  {

    String email = "nobody@gmail.com";
    String nameOnly = email.substring(0,email.indexOf('@'));
    System.out.println(nameOnly);
  }
}

Answer 2

You can use regex + replaceAll method of string for eliminate it

sample:

    String s = "Rod_Algonquin@company.co.nz";
    String newS = s.replaceAll("@(.*).(.*)", "");
    System.out.println(newS);

will work on different sites extension.

if you want .org , .net , etc then you need to change the regex @(.*).(.*)

Answer 3

make sure the email format be correct then use "split" method to split the string from '@' character's position and use first portion of results.

var str = "username@amailserver.com"; 
var res = str.split("@");
var username = res[0];
