Java 生成随机数

使用 SecureRandom

import java.security.SecureRandom;

public class Main {
    public static void main(String[] args) {
        SecureRandom secureRandom = new SecureRandom();
        int randomInteger = secureRandom.nextInt(10);
        System.out.println("Secure random Integer: " + randomInteger);
    }
}

使用 Apache Commons 的 UniformRandomProvider

在 Maven 中添加依赖:

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-rng-simple</artifactId>
    <version>1.3</version> <!-- Replace with the version you want -->
</dependency>

然后：

import org.apache.commons.rng.simple.RandomSource;
import org.apache.commons.rng.UniformRandomProvider;

public class Main {
    public static void main(String[] args) {
        UniformRandomProvider rng = RandomSource.create(RandomSource.JDK);
        int randomInteger2 = rng.nextInt(10);
        System.out.println("Random Integer from UniformRandomProvider: " + randomInteger2);
    }
}
