2. Java Random number between 1 and 10 Sometimes we have to generate a random number between a range. For example, in a dice game possible values can be between 1 to 6 only. Below is the code showing how to generate a random number between 1 and 10 inclusive. Random random = new Ra...

在Java 中,生成随机数的场景有很多,所以本文我们就来盘点一下 4 种生成随机数的方式,以及它们之间的区别和每种生成方式所对应的场景。 Random Random 类诞生于 JDK 1.0,它产生的随机数是伪随机数,也就是有规则的随机数。Random 使用的随机算法为 linear congruential pseudorandom number generator (LGC) 线性同余...

从原理来看，SecureRandom内部使用了RNG (Random Number Generator，随机数生成)算法，来生成一个不可预测的安全随机数。但在JDK的底层，实际上SecureRandom也有多种不同的具体实现。有的是使用安全随机种子加上伪随机数算法来生成安全的随机数，有的是使用真正的随机数生成器来生成随机数。实际使用时，我们可以优先获取...

As we have seen, Java provides us with a lot of classes and methods for generating random numbers. However, there are also third-party APIs for this purpose. We’re going to take a look at some of them. 3.1.org.apache.commons.math3.random.RandomDataGenerator ...
