       Scanner scnr = new Scanner(System.in);
       boolean hasDigit;
       String passCode;
      
       hasDigit=false;
       passCode=scnr.next();
      
       for(int i=0;i        {
           if(Character.isDigit(passCode.charAt(i)))
           {
               hasDigit=true;
               break;
           }
