Random number generator generating same numbers each time application is ran [duplicate]

Answer 1

You are seeding the Random instance always with the same seed 1000 here:

Random rnd = new Random(1000);

this will not do that since the current time is used as seed:

Random rnd = new Random();

Have a look at the constructor which takes an int.

Providing an identical seed value to different Random objects causes each instance to produce identical sequences of random numbers.
