Thread Safety and Shared Resources
Code that is safe to call by multiple threads simultanously is called thread safe. If a piece of code is the thread safe, then it contains no race conditions. Race condition only occur when multiple threads update shared resources. Therefore It is important to know what the resources Java threads share when executing. Local Va
