Description

Lessons Learned:
I learned a lot about concurrent programming in Java. I learned how to set up threads that correspond to certain tasks and to increment time by having them sleep. I learned the difference between pausing and stopping a thread, as well as how to restart and interrupt a thread that is waiting or sleeping. I also learned a lot about Java swing and how to update values in a JLabel based on values returned by a threaded process. I found this program challenging and fun.
