hi evrey one i have this sheet and i Wrote this program

The program contains no errors But the output is false
I want to know what mistakes in my program :confused:

can any one help me ? :(

Question

Write a program to read an email address and do the following:

1- Get the full name part from email addresses, assign it to a string (Fullname) in this format : Last, First
2- Get email domain and assign it to a string variable (Domain)
3- Display name and domain .


Note : email is entered in this format (first.last@domain)

Ex:
Input email : ali.alsaleh@ksu.edu.sa
you should output :
Full Name is : Alsaleh, Ali
Domain is : ksu.edu.sa

and this is my program :>

import java.util.*;
public class sheet6q2
{
public static Scanner console = new Scanner (System.in);
public static void main (String[]args)
{
String firstname,lastname,Domain , email ;

System.out.println("plz entar your email :");
email= console.next();

firstname = email.substring(0,'.');

lastname= email.substring('.','@');


Domain= email.substring('@',email.length() - 1);


System.out.println("full name is :"+" "+ lastname+","+firstname +" Domain is :"+ " "+ Domain);

}
}

The problem is the substring method needs an int as a parameter...
try using the indexOf method in addition.

ex:
firstName = email.substring(0, email.indexOf('.'))

that should work

thx alot :) I've done your advice But there are also errors in outputs :(

firstname = email.substring(0, email.indexOf('.'));



lastname= email.substring('.', email.indexOf('@'));



Domain= email.substring('@', email.length()-1);

:confused:

Again, with the substring method, you can only use int's as parameters.
With:

 lastname= email.substring('.', email.indexOf('@'));

you are passing in char's, if you are looking for char's, you need to use the indexOf method. you had the @ correct, so now try the below example, and see if you can figure out the last one on your own.

 
lastname= email.substring((email.indexOf('.') + 1), email.indexOf('@'));

good luck

Another option is to call String#split("\\.") using the period as the regex to split on:

    String test = "foo.bar";
    String[] tokens = test.split("\\.");
    System.out.println(Arrays.toString(tokens));

Much luck!
