I followed these steps to…

We’ve also described how local variables are private to a thread and how references can be shared among threads, allowing them to communicate via common fields. The next step is synchronization: coordinating the actions of threads for a predictable outcome. Synchronization is particularly important when threads access the same data; it’s surprisingly easy to run aground in this area. Synchronization constructs can be divided into four categories: Simple blocking…
