This repository contains Java code that demonstrates concurrent auditing operations.
The App class serves as the entry point for the application. It demonstrates concurrent auditing
operations add remove and inStock by utilizing a fixed thread pool of three threads.
In the synchronized add and remove methods should display their "START" messages in order and complete
their operations before displaying their corresponding "END" messages. Also notice that whichever synchronized
method add od remove wins the race and locks the Audit object it will be able to finish running before the
other synchronized method is allowed to start
The thread IDs for the "START" and "END" messages of add and remove should match, indicating that the same thread is performing the entire operation.
Since inStock is not synchronized, it's "START" and "END" messages may appear interleaved with the "START"
and "END" messages of add and remove, and their thread IDs may differ.
