Java随机数api演进的相关内容

硬核 - Java 随机数相关 API 的演进与思考（下）

本系列将 Java 17 之前的随机数 API 以及 Java 17 之后的统一 API 都做了比较详细的说明，并且将随机数的特性以及实现思路也做了一些简单的分析，帮助大家明白为何会有这么多的随机数算法，以及他们的设计思路是什么。本系列会分为两篇，第一篇讲述 Java 随机数算法的演变思路以及底层原...

硬核 - Java 随机数相关 API 的演进与思考（上3）

Java 17 之前一般如何生成随机数以及对应的随机算法首先放出算法与实现类的对应关系：使用 JDK 的 API1.使用 java.util.Random 和基于它的 API：Random random = new Random(); random.nextInt();Math.random() 底...

硬核 - Java 随机数相关 API 的演进与思考（上2）

SEED 的来源由于 JDK 中所有的随机算法都是基于上一次输入的，如果我们使用固定 SEED 那么生成的随机序列也一定是一样的。这样在安全敏感的场景，不够合适，官方对于 cryptographically secure 的定义是，要求 SEED 必须是不可预知的，产生非确定性输出。在 Linux ...
