    //Write your code here class MyRegex{ public String pattern;

    public MyRegex() {
    this.pattern = "^(\\d{1,2}\\.|[01]\\d{2}\\.|2[0-4]\\d\\.|25[0-5]\\.){3}(\\d{1,2}|[01]\\d{2}|2[0-4]\\d|25[0-5])$";
}

    }

    class MyRegex { String pattern = "^((25[0-5]|2[0-4]\d|1\d{2}|0\d{2}|\d{1,2})\.){3}" + "(25[0-5]|2[0-4]\d|1\d{2}|0\d{2}|\d{1,2})$"; }

    This is a really practical exercise! Writing a MyRegex class to validate IP addresses not only tests your understanding of regular expressions but also teaches you how to handle real-world data validation. cbtf turbo 247 login
