    public static boolean isPrime(int num) {
        if (num <= 1) {
            return false;
        }
        for (int i = 2; i <= Math.sqrt(num); i++) {
            if (num % i == 0) {
                return false;
            }
        }
        return true;

        // Prompt the user to enter a number
        System.out.print("Enter a number: \n");
        int userInput = scanner.nextInt();
       
        // Display prime numbers less than the user's number
        System.out.print("Prime numbers are " + userInput + ": ");
        for (int i = 2; i < userInput; i++) {
            if (isPrime(i)) {
                System.out.print(i + " ");
            }
        }
       
        // Close the scanner
        scanner.close();
    }
}
