What are the differences between synchronized and reentrant functions?

Can you explain the differences between synchronized and reentrant functions?

Sure! Synchronized functions are designed to prevent concurrent access, ensuring that only one thread can execute them at a time.

What about reentrant functions? How do they differ from synchronized ones?

Reentrant functions can be interrupted and safely called again before the previous executions complete. They don't hold state.

So, can a function be both synchronized and reentrant?

No, a function cannot be both. Synchronized functions block other threads, while reentrant functions allow concurrent execution.

Can you give an example of each type?

Certainly! A synchronized function might be a method that updates a shared resource, while a reentrant function could be a mathematical calculation that doesn't rely on shared state.
