Join Peggy Fisher for an in-depth discussion in this video Using simulations, part of Java Essential Training for Students.
- Did you know that object oriented programming languages…were originally used most frequently…for two types of applications:…computer simulations and graphical user interfaces.…Computer simulations attempt to mimic real world activities…so that their processes can be improved…or so that users can better understand…how the real world operates.…Discrete-event simulation is a good option for problems…that can be modeled as individual events…that take place at very specific times.…
Key activities are randomly generating times and durations…based on empirical data,…and accumulating statistics as the simulation runs.…Let's take a look at an example.…You could simulate the activity in a parking garage…as the entries and departures of cars…and the loss of customers who can't enter…because the garage is full.…This can be done with two model classes…a car class and a garage class,…and three other supporting classes…an event class, a schedule and a monitor.…
The schedule will manage the events,…and the monitor will accumulate the data.…
