update in class Experiment

graphUpdate

public void graphUpdate()
Specified by:
graphUpdate in interface IExperiment
Overrides:
graphUpdate in class Experiment

step

public void step()
This method runs the experiment one time and plays sounds depending on the outcome.

Specified by:
step in interface IExperiment
Overrides:
step in class Experiment

reset

public void reset()
