        String passCode;
        hasDigit = false;
        passCode = scnr.next();
        // the string is passCode and not userInput
        // also you didn't declare let0, let1, let2
        int let0 = passCode.charAt(0);
        int let1 = passCode.charAt(1);
        int let2 = passCode.charAt(2);
        if ((Character.isDigit(let0) || Character.isDigit(let1) || Character.isDigit(let2))){
        hasDigit = true;
        }
        if (hasDigit) {
        System.out.println("Has a digit.");
        }
