En Java, il existe la méthode Math.Random(). Générer un nombre aléatoire est une fonctionnalité souvent utilisée en développement. En Java , il existe la méthode Math.Random() qui génère un nombre aléatoire compris entre 0 et 1, mais il n'est pas possible de changer les limites de ce nombre (voir notre astuce connexe pour arrondir un nombre à n décimales en Java ).

In this tutorial, we will see Java Random nextDouble method.It is used to generate random double. It returns the next pseudorandom, uniformly distributed double value between 0.0 and 1.0 from this random number generator’s sequence. Syntax [crayon-6085e41f5a686756102746/] Here random is object of the java.util.Random We can also use java math.random method to generate a random number within a specific range. In order to achieve this, we need to multiply the return value of the random() method with the maximum range.

调用这个Math.Random ()函数能够返回带正号的double值，该值大于等于0.0且小于1.0，即取值范围是 [0.0,1.0)的左闭右开区间，返回值是一个伪随机选择的数，在该范围内（近似）均匀分布。. 例子如下：. Random ()：创建一个新的随机数生成器。. Random (long seed)：使用单个 long 种子创建一个新的随机数生成器。. 我们可以在构造Random对象的时候指定种子（这里指定 Random MethodThe JavaScript Math.random() method is an excellent built-in method for producing random numbers. When Math.random() is executed, it returns a random number that can be anywhere between 0 and 1.
