| Bubble Sort
| Bi-Directional Bubble Sort
| Quick Sort

Now start each of the applets, one by one, by clicking on them with the mouse. Notice anything? Yes! The applets are running side by side at the same time! Notice anything else? Yes! You can also scroll this page or bring up one of your browser's panels at the same time that the three sorting applets sort their data. All of this is due to the power of threads.
