Constructor Detail

Sim_pascal_obj

public Sim_pascal_obj(String name,
                      double prob,
                      long successes)
Constructor with which Sim_system is allowed to set the random number generator's seed

Parameters:
name - The name to be associated with this instance
prob - The probability of success
successes - The number of successes

Sim_pascal_obj

public Sim_pascal_obj(String name,
                      double prob,
                      long successes,
                      long seed)
The constructor with which a specific seed is set for the random number generator

Parameters:
name - The name to be associated with this instance
prob - The probability of success
successes - The number of successes
seed - The initial seed for the generator, two instances with the same seed will generate the same sequence of numbers
