Identify and fix code in a multithreaded environment

Threading issues arise when multiple threads work with shared data and when they’re dependent on other threads. This section identifies the data that you need to be careful with when working with multiple threads, the operations (or methods) that can lead to threading issues, the order of operations, and how to get around all of these issues. Let’s get started with identifying the data that the threads can share among themselves. Only when you know what data can be shared, will you be able to identify how it can be fixed.
