This method is properly synchronized to allow correct use by more than one thread. However, if many threads need to generate pseudorandom numbers at a great rate, it may reduce contention for each thread to have its own pseudorandom-number generator. ...

7. Generate Random byte array We can generate random bytes and place them into a user-supplied byte array using Random class. The number of random bytes produced is equal to the length of the byte array. Random random = new Random(); ...
3.2.it.unimi.dsi.util.XoRoShiRo128PlusRandom Certainly, this is one of the fastest random number generator implementations. It has been developed at the Information Sciences Department of the Milan University. The library is also available atMaven Centralrepositories. So, let’s add the dependency:...
