Tīmeklis2008. gada 21. febr. · Random.nextInt(int) The pseudo random number generator built into Java is portable and repeatable. If two Random objects are created with the same seed and the same sequence of method calls is made for each, they will generate and return identical sequences of numbers in all Java implementations.. I have seen … Tīmeklis2024. gada 26. sept. · This generator inherits from java.util.Random. However, if we take a look at the JavaDoc, we realize that there's only one way of using it — through the nextInt method. Above all, this method is only available with the zero- and one-parameter invocations. Any of the other invocations will directly use the …
