        String originalString = "Java123 Programming! is #Fun.";
        System.out.println("Original String: " + originalString);

        // Step 2: Use replaceAll() with a regular expression
        // [^a-zA-Z] matches any character that is NOT an alphabet (a-z or A-Z)
        String cleanedString = originalString.replaceAll("[^a-zA-Z]", "");

        // Step 3: Print the cleaned string
        System.out.println("Cleaned String: " + cleanedString);
