class MyRegex { public static String pattern = "^((25[0-5]|2[0-4]\d|1\d\d|0?\d\d|0?\d)\.){3}" + "(25[0-5]|2[0-4]\d|1\d\d|0?\d\d|0?\d)$"; }
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
pattern = "((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)";
String from0to199="[0-1]?\d{1,2}"; String from200to249="2[0-4]?\d"; String from250to255="25[0-5]"; String from0to255 ="(" + from0to199 + "|" + from200to249 + "|" + from250to255 + ")"; String dot="\."; String pattern=from0to255+dot+from0to255+dot+from0to255+dot+from0to255;
Seriously, Is this a Java exercice?!
