This exercise consists of a Call Center model where 3 types of employee work: OPERATOR, SUPERVISOR and DIRECTOR.
The main objective is to handle incoming calls and assign them to employees through a Dispatcher.
The main solution is to use threads were Employees may work (attend calls, that are just invocations to sleep methods).
In order to handle more calls than the employees can handle, they are put in a concurrent queue and wait until some employee becomes available.
There are a couple of informational logging calls left intentionally to understand the code easily while running tests.
Java JDK 8 and Maven are required to run the project.
As in any Maven project, it may be required to run
mvn clean install- Sebastian D'Agostino
