import java.util.Random;

public class RandomEmojiGenerator {

    // Array of commonly used emojis
    private static final String[] EMOJIS = {"😊", "🚀", "🌟", "🎉", "👾", "💻", "📚", "🎨"};

    public static void main(String[] args) {
        // Generate a random index to pick an emoji from the array
        int randomIndex = getRandomIndex();

        // Get the randomly selected emoji
        String randomEmoji = EMOJIS[randomIndex];

        // Display the result
        System.out.println("Random Emoji: " + randomEmoji);
    }

    // Method to generate a random index within the array size
    private static int getRandomIndex() {
        Random random = new Random();
        return random.nextInt(EMOJIS.length);
    }
}

How It Works

1. Emoji Array: We start by defining an array (EMOJIS) containing a variety of emojis. You can customize this array with your favorite emojis or expand it as needed.

2. Random Index: The getRandomIndex method utilizes the Random class in Java to generate a random index within the bounds of the emoji array.

3. Display Result: The main method then uses the random index to fetch a randomly selected emoji from the array, which is then printed to the console.

Running the Code

To run this code, simply copy it into a Java file (e.g., RandomEmojiGenerator.java) and execute it using your preferred Java compiler or integrated development environment (IDE). You’ll witness the magic of a different emoji appearing each time you run the program.
