running at the same time in the process where your code is located, these threads may run the code at the same time. If the result of each run is the same as that of a single-threaded operation, and the value of other variables is the same as expected, it is thread-safe. The same instance object of a thread-safe counter class will not have a miscalculation if it is used by multiple threads. Obviously you can divide the collection class into two groups, thread-safe and not-thread-safe. Vector is
