The general contract of setSeed is that it alters the state of this random number generator object so as to be in exactly the same state as if it had just been created with the argument seed as a seed.

Setseed java

Java 8 Programming Object Oriented Programming. The random object can be reseeded using the setSeed() method in the class java.security.SecureRandom. This method requires a single parameter i.e. the required seed byte array and it … Move your setSeed out of the loop. Java’s PRNG is a linear congruential generator, so seeding it with sequential values is guaranteed to give results that are correlated across iterations of the loop. ADDENDUM.
