Question

Set hasDigit to true if the 3-character passCode contains a digit.

public class CheckingPasscodes {

public static void main (String [] args) {

boolean hasDigit = false;

String passCode = "";

int valid = 0;

passCode = "abc";

/* Your solution goes here */

if (hasDigit) {

System.out.println("Has a digit.");

}

else {

System.out.println("Has no digit.");

}

return;

}

}

Answer 1

Program:

Sample output:

if passCode = "ab3";

Code to copy:

public class CheckingPasscodes

{

     public static void main (String [] args)

     {

          boolean hasDigit = false;

          String passCode = "";

          int valid = 0;

          passCode = "abc";

          //check each character in the passcode whether

          //the passcode has a digit or not

          for(int index = 0;index < passCode.length();index++)

          {

              char charcter=passCode.charAt(index);

              //check the character is a digit or not

              if(Character.isDigit(charcter))

              {

                   //set the boolean value hasDigit as true, if

                   // the character is a digit

                   hasDigit = true;

              }

          }

          //display a message "Has a Digit, if the passcode

          //contains a digit

          if (hasDigit)

          {

              System.out.println("Has a digit.");

          }

          //display a message "Has no digit, if the passcode

          //does not contain a digit

          else

          {

              System.out.println("Has no digit.");

          }

          return;

     }
