Consider a simulator of a machine that fills boxes of breakfast cereals. The filling is simulated by repeatedly calling a method that drops a certain amount of cerals into the box during a certain interval of time. Both the amount of cereals and the interval of time for a drop are subject to small random variations. As a safety measure, the machine has a shutoff device that shuts off itself if the content of the box exceeds a certain threshold.Design, code an implement the simulator. Use a thread to repeatedly call the drop method. Use a guarded suspension pattern for the shutoff device. Hint: to test the safety device, your drop method may systematically return true.
