生成给定长度的随机字符串

import random
import string

def generate_random_string(length):
    characters = string.ascii_letters + string.digits + string.punctuation
    return ''.join(random.choice(characters) for _ in range(length))

# 示例用法
random_string = generate_random_string(10)
print(random_string)

import java.security.SecureRandom;

public class RandomStringGenerator {
    private static final String CHARACTERS = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!@#$%^&*()";

    public static String generateRandomString(int length) {
        SecureRandom random = new SecureRandom();
        StringBuilder sb = new StringBuilder(length);
        for (int i = 0; i < length; i++) {
            int randomIndex = random.nextInt(CHARACTERS.length());
            sb.append(CHARACTERS.charAt(randomIndex));
        }
        return sb.toString();
    }

    // 示例用法
    public static void main(String[] args) {
        String randomString = generateRandomString(10);
        System.out.println(randomString);
    }
}
