Thanks You So Much Durga sir................🙏🙏🙏🙏🙏🙏

Instead of m.group(0).equals(args[0]) , we can write the regex as "^(0|91)?[789]\\d{9}$"

[@MrAnkit812]

Sir, Matcher m = p.matcher(args[0]); , I didnn't understand why we put "args[0]" in it. can you please explain once again and another thing is if we pass args[0] then it will take just first part of the number that is --> either 0 or 91 or It will take whole number as input

Great video. One could also return Boolean m.matches(args[0]);

The easiest way is: if (m.matches()) valid else invalid

[@sunnymaurya4633]

Here is the explanation of both method boolean matches() test whether the regular expression matches the pattern. boolean find() finds the next expression that matches the pattern.

import java.util.regex.*; import java.util.*; public class Regex { public static void main(String[] args) { Scanner scan = new Scanner(System.in); Pattern p = Pattern.compile("(0|91)?[7-9][0-9]{9}"); System.out.print("Enter your mobile number: "); String mobile = scan.nextLine(); Matcher m = p.matcher(mobile); if(m.find() && m.group().equals(mobile)) { System.out.println("Valied"); } else { System.out.println("Invalied"); } } }

Bro did you find solution for this

[@anuraag3103]

Simpler Code: Pattern pattern = Pattern.compile("(0|91)?[7-9][0-9]{9}"); Matcher matcher = pattern.matcher("7894534567"); if(matcher.matches()) { System.out.println("Valid Mobile number"); } else { System.out.println("Invalid mobile number"); }
