i cannot understand the following line , can anybody provide me some example for the below statement?

If two instances of Random are cre

Answer 1

The numbers are not really random, given the same starting conditions (the seed) and the same sequence of operations, the same sequence of numbers will be generated. This is why it would not be a good iea to use the basic Random class as part of any cryptograhic or security related code since it may be possible for an attacker to figure out which sequnce is being generated and predict future numbers.

For a random number generator that emits non-deterministic values, take a look at SecureRandom.

See Random number generation, Computational methods on wikipedia for more info.
