java regex issue with email validation

I am trying to validate email in java. Below is the code:

String mail = "[email protected]";
    String regex = "^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*(\\.[A-Za-z]{2,})$";
    if(mail.matches(regex)){
        System.out.println("valid email");
    };

Now i want to restrict the length of Text1 and Text2 to 10 characters and length of Text3 to 5 characters.

I tried with this regex but did not work - ^[_A-Za-z0-9-]+(\.[_A-Za-z0-9-]{2,}+)*@[A-Za-z0-9]+(\.[A-Za-z0-9]+)*(\.[A-Za-z]{2,})$

How do i achieve this? Thanks.

^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]+)*@[A-Za-z0-9-]+(\\.[A-Za-z0-9-]+)*(\\.[A-Za-z]{2,})$ I have used this another approach.

Here's the regex:

String regex = "^[_A-Za-z0-9-]+(\\.[_A-Za-z0-9-]{0,10})*@[A-Za-z0-9]+(\\.[A-Za-z0-9]{0,10})*(\\.[A-Za-z]{0,5})$";

This doesn't count dots as a character, uses {n, m} syntax, it limits the number of characters to be between n and m occurrences.
