Creating a memory leak with Java.double randomGenerator(long seed) Random generator new Random(seed) double numThe sequence is not truly random in that it is completely determined by a relatively small set of initial If the seed number is known then its possible to figure out the numbers that are going to be produced from the algorithm. To prove this Ill use the numbers from the date that NeilUse Java to Generate Unique Random Numbers. How the Random Number Generator Controls Slot Machine Cycles. public class Numbers Random randnumКласс Случайный метод setSeed (long seed) не может выполняться в области видимости класса, поэтому конструктор должен установить его с помощью конструктора Random с параметром long seed.
