Question

Please help....the only line that can be modified is /* Your solution goes here */.

Everything else should remain the same.

I submitted hasDigit = Character.isDigit(passCode.charAt(3)); but it's wrong....thank you

import java.util.Scanner;

public class CheckingPasscodes {
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
boolean hasDigit;
String passCode;

hasDigit = false;
passCode = scnr.next();

/* Your solution goes here */

if (hasDigit) {
System.out.println("Has a digit.");
}
else {
System.out.println("Has no digit.");
}
}
}

import java.util.Scanner;

public class CheckingPasscodes {

    public static void main(String[] args) {
        Scanner scnr = new Scanner(System.in);
        boolean hasDigit;
        String passcode;
        hasDigit = false;
        passcode =scnr.next();
        hasDigit = passcode.matches(".*[0-9].*"); //.* means that any character can occur zero or more times
        if(hasDigit)
        {
            System.out.println("Has a digit");

        }
        else
        {
            System.out.println("Has no digit");
        }

    }
}
