在java中生成一定长度的随机单词？

import java.util.Random;

public class RandomWordGenerator {
    private static final String CHARACTERS = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
    private static final Random RANDOM = new Random();

    public static String generateRandomWord(int length) {
        StringBuilder sb = new StringBuilder(length);
        for (int i = 0; i < length; i++) {
            int index = RANDOM.nextInt(CHARACTERS.length());
            sb.append(CHARACTERS.charAt(index));
        }
        return sb.toString();
    }

    public static void main(String[] args) {
        int wordLength = 10;
        String randomWord = generateRandomWord(wordLength);
        System.out.println("Generated Random Word: " + randomWord);
    }
}
