Race Condition with Static Class?

Question

Let\'s say I have a static class with a static method.

Multiple threads can call this static method concurrently.

Is there a potential for a race condition u

Answer 1

First off, a method is simply a piece of code residing at an address. Each thread calling a method will have a copy of that method and its local variables on its own private stack. So in case a, provided there are no other catches, it should be thread-safe.

Case b depends on a lot of factors:

• are you actually accessing those member variables?
• how are you accessing them: only reads, reads + writes, etc.
• what kind of member variables: data structures, single values.
• do you have any synchronization in place?
• etc.

Generally though, assuming you do access the class members, it should not be considered thread-safe.
