Random seed java
TīmeklisThe java.util.Random class is used to generate random numbers. Java Random class objects are thread safe. It provides several methods to generate random numbers of type integer, double, long, float etc. Note: Random class objects are not suitable for security sensitive applications so it is better to use java.security.SecureRandom in … Tīmeklis我設法根據種子創建了一個隨機序列，但現在我正在嘗試其他方法。 基本上，它會生成一個數字 基於種子 ，然后檢查該數字是否已在數組中，然后檢查是否在數組中，然后 …
