Priority Scheduler (Java)
11/2019 - 12/2019
Simulated priority-based preemptive CPU scheduling by building a system that allows the concurrent
running of vehicles in multiple tunnels using Java concurrent package and thread class.
Used synchronized keyword, mutexes, condition variables to ensure thready safety and concurrency.
Utilized factory pattern to implement an object oriented design.
Ensured that the number of vehicles does not exceed the capacity of each tunnel and ambulances have
